A Perfect Finale to Off-Campus and Briar U
The Legacy was everything I hoped for and more—a perfect conclusion to Elle Kennedy’s Off-Campus world. It felt like catching up with old friends and seeing how far they’ve come since we first met them. I laughed, swooned, and even teared up at times—it’s such a satisfying send-off for a series I’ve loved so much. One of the best parts of this book is how we get to spend time with each of the beloved couples: Hannah & Garrett – Still as sweet and solid as ever, proving that their love is built to last. Grace & Logan – Fun, flirty, and full of chemistry, but also showing real growth in how they handle life’s challenges together. Allie & Dean – Emotional, heartfelt, and just as fiery as they’ve always been—Dean never fails to make me smile. Sabrina & Tucker – Tender, mature, and grounded, yet still so full of love. Their storyline was especially touching to see. Elle Kennedy weaves their stories together seamlessly, balancing humor, heartfelt moments, and romance. Each section gives closure while still keeping things exciting—it’s like getting four mini love stories wrapped into one beautiful package. I highly recommend reading The Legacy after finishing both the Off-Campus and Briar U series. It brings everything full circle, and you’ll appreciate all the cameos, callbacks, and little details so much more. Plus, it’s the perfect lead-in before starting the new Campus Diaries series, since you get that emotional closure first. Overall, The Legacy is a heartfelt, fun, and incredibly satisfying finale that left me with a huge smile. If you loved the Off-Campus or Briar U books, this one is a must-read.

The Legacy
Format: Kindle
I had so much fun with this book! Getting to see every couple again and see them navigate through their challenges in their unique, funny ways. Loved it! Tucker is still my favorite guy. Also loved how they made this like a twisted sisterhood of the traveling pant’s story. So funny.

Off-Campus Conclusion
Format: Kindle
This review is one of the hardest ones I've ever written. The Off-Campus series is without a doubt one of the best series I've ever read. I have loved these characters, their stories, and the growth we've seen along the way. I love the love they all share. A quick refresher of the 4 previous books and how I rated them: The Deal - Garrett and Hannah - 5/5 (10/5 if it were an option.) The Mistake - Logan and Grace - 5/5 The Score - Dean and Allie - 5/5 The Goal - Tucker and Sabrina - 4/5 I was so excited about this book! A glimpse into some of my favorite characters, and where are they now. But, as much as it breaks my heart to say it, this book fell flat. First, let's talk about the pros. 1. Throughout the first four books, one of my favorite parts was the bromance and friendships between Garrett, Logan, Dean, and Tucker. THIS BOOK DOES SUCH A GOOD JOB WITH THAT, AND OMG IT MAKES MY HEART HAPPY. Their friendship is front and center and I loved every part of it. 2. Logan and Grace's and Tucker and Sabrina's installments in this book are the best in my opinion. I do wish that the rest of the gang could have been there for Logan and Grace's wedding, but it was oddly fitting for them. 3. This book is laugh-out-loud funny. 4. I love, love, loved watching Sabrina fighting for her man when he got arrested. Like yes, queen! Now for the cons: 1. The biggest reason this book physically pained me is how Garrett and Hannah's part was written. It was so far out of character and literally broke my heart. Their story is the last one of this book. They're my favorite couple from the series, and the part of The Legacy I was looking forward to the most. And boy, it let me down and broke my heart. I actually went back and reread The Deal not long after finishing The Legacy because I was so confused by this part of the book. I had to go back and restore my love in Garrett and Hannah. In The Legacy, I feel Garrett does not have his life together, and he's mean, especially to Hannah. Like we get it, Phil Graham is the worst, but Garrett never used to take it out on Hannah or let it affect their relationship, but boy does it ever here. And Hannah hiding the fact she's pregnant from Garrett for so long?! What is up with that?? Ugh, it literally hurts to be writing this because I looked forward to this and wanted to love it so much but just didn't. 2. Allie could not have been more immature in their section. I get she was scared, but girlfriend, c'mon. When Dean Di Laurentis offers you a ring and his last name, you don't tell the man no. A rating of the different couples parts of this book: The Pact - Logan and Grace - 4/5 stars The Proposal - Dean and Allie - 3/5 stars The Honeymoon - Tucker and Sabrina - 4/5 The Legacy - Garrett and Hannah - 2/5 As grateful as I was to get to go back and hang out with the Off-Campus crew again, it just fell flat for me. I wish we could get a redo. See them all now. How's marriage going? How are the kids? How's work? Get to laugh it up with the gang again, and fall in love with the love they share all over, especially Hannah and Garrett. I feel this book lacked the finality and closure this beautiful series deserved. Truthfully, it would have been better off without this installment altogether (Which I literally HATE to say.)

LOVED THIS BOOK!!
Format: Kindle
*NO SPOILERS PART OF MY REVIEW* I was eagerly anticipating this book ever since I learned it was coming out! I watched so many TikToks about this series and it made me feel so validated in my obsession for the Off Campus series and the OC couples. Therefore, I could not wait to read The Legacy as soon as it came out. I refreshed my Kindle app and there it was! I read all night, and slept for maybe 1 hour but I finished the book within 12 hours of it being released. I was SO pleased. This book was fabulous. Though it is 4 novellas (one for each couple) Elle Kennedy did an amazing job of weaving the four stories together and making it seamless. I really appreciated the continuity throughout the whole book. Seeing the group's dynamic was a total highlight of this book. I absolutely loved that we got to see their messages in the group chat and see how their friendships have stood the test of time and distance after their college days are over. I LOVED seeing the mentions of other characters in the Briar U/ Off-Campus universe as well. It reminded me of why I love this series so much. One thing, not a real spoiler but the epilogue is only about one couple, not all 4 like I had hoped and expected. I really hope we see more from the Off-Campus/Briar U universe in the future. If you love this series, you will really enjoy this book. I HIGHLY RECOMMEND READING THE WHOLE SERIES. IN ORDER. INCLUDING THIS AMAZING BOOK. ****CAUTION SPOILERS AHEAD**** I appreciated that Elle Kennedy added more to Grace and Logan's story given that a version of it was already published 2 years ago (?). I really liked their story. At first I was a little annoyed that it ended on sort of a cliff hanger, but once I read the whole book, it made sense because other novellas in this book ended the same way. Allie and Dean are my favorite couple in the Off-Campus series, followed by Hannah and Garrett. Allie and Dean's story in this book was great. I really loved getting to see them together again. The main conflict/ problem in their story was surprising to me. Allie's hesitation about engagement, wedding, babies, seemed a little bit uncharacteristic of her. She is SUCH a hopeless romantic, that seeing her be apprehensive about all of those things was confusing for me as a reader and a fan. But overall, I really enjoyed seeing Dean and Allie again. I love Dean so much. He is such an innately good person and so is Allie. I'm sad that there was no "glimpse into the future" for A&D in the epilogue because I would have LOVED to see them start a little family and maybe name their son Beau since Beau Maxwell was such a big part of their story. Sabrina and Tucker's story was also great. I appreciated that the author gave them a conflict in this book that in my opinion was never really resolved/addressed in The Goal. Their communication skills as a couple was beyond bad and frustrating! Tucker's admission to Sabrina that he is unhappy in his job coming as a surprise to Sabrina was bizarre. I enjoyed seeing them as parents to a toddler, so cute! Finally, Hannah and Garrett. The original Off-Campus couple. The people that started it all. I appreciated the premise of their novella, but bringing Garrett's abusive father back into the storyline, but only in a novella was unfair. There is SO SO SO much to say and unpack with regards to that. Shoehorning it into a brief novella was frustrating as a reader because it felt like that needed to be a whole full-length book itself. And Hannah holding off on telling Garrett about the pregnancy was also strange and unlike them. Garrett switching his opinion so quickly about being a dad was way too rushed. I feel like they were a couple who was pretty good at communication so seeing how Hannah handled this situation in this book was surprising. I would have really loved to see Garrett acknowledging that he has a lot of childhood trauma to work through and process in therapy! That would have been some real character development for him. Also, the lack of a wedding for them was upsetting because I feel like they deserve that and as a reader, I would have loved to see thatI!! Lastly, The epilogue was also a bit of a let down as I expected it to be a flash forward for all 4 couples, but it was just for Hannah and Garrett and it wasn't really a flash forward at all. *END OF SPOILERS* READ THIS BOOK!!! THANK YOU ELLE KENNEDY!!!!

Epilogues that left me wanting more
Book Review *minor spoilers* 3.5 stars I absolutely ADORE the Off Campus series by Elle Kennedy. Every book was fun, spicy, and dealt with real world problems, but with happy ever afters of course! I was SO excited to read The Legacy. An extended epilogue book dedicated to these characters?? Yes, absolutely love that idea. While it was very fun catching up with our favorite couples and seeing where they're at 2 years after their stories ended in their prospective books, I felt a little let down by most of them. I think my favorite epilogue story of the 4 couples was Grace and Logan. They kicked off the book with a bang. There was humor, emotions, spice, more humor. Plus the elopement!! I only wish we could have seen that part actually play out instead of a cliffhanger and then hearing about it through other characters later on. Dean and Allie. Gosh I loved this couple so much; their book (The Score), was my favorite of the original books. But Allie's character frustrated me so much when she didn’t want to accept Dean's proposal! Come ON girl!! Sabrina and Tucker. Their book was my least favorite of the original books, largely due to the plot focused around her pregnancy. Pregnancy tropes are just not my jam. And again, least favorite epilogue couple. Tucker opening two successful bars in Boston within 2 years - wildly unrealistic. Sabrina graduating Harvard Law while pregnant and raising her daughter; somewhat more realistic. Their story in the epilogue was entertaining, but it just didn’t do it for me. And Garrett and Hannah. My OG favorite couple. I loved their epilogue. I did not love that Hannah was so afraid to tell Garrett about her surprise pregnancy. But her reasoning was *somewhat* understandable. I will read anything I can get my hands on about this couple. But I just wanted MORE. More with the storyline about Garrett going public about his father's abuse. More about Hannah's career. More about G and H being parents - tell me about their kids! At least what are their names! Overall it was a fun way to wrap up the series. While I felt left wanting more, it's safe to say I probably wouldn’t ever be fully satisfied. Can Elle Kennedy please just write endless books about this characters? K, thanks bye!
