The Do-Over: A Novel - Suzanne Park

From the author of the "genuinely funny" and "delightful" Loathe at First Sight (NPR) and "cinematic, charming" So We Meet Again (Emily Henry), a fun rom-com about a young Korean-American woman having to return to college after discovering she's a few credits shy of completing her degree-only to find one of her TAs is her old college boyfriend.
Bestselling author Lily Lee is on a short deadline to deliver her new career guide How to Land the Perfect Job, and she's been interviewing at all the top companies around town. But when she's offered a coveted position at her dream company, the employer's background check reveals she never actually finished her college degree. Unbelievably, her worst nightmare has come true.
Lily returns to her alma mater to relive her senior year of college, after walking across the stage at graduation a decade earlier. Just as she starts getting used to the idea of being a student again, things get even more weird and chaotic when she discovers her computer science TA is her old college boyfriend, Jake Cho.
As Lily and Jake reconnect, she sees that her late-blooming ex has done well for himself: the handsome, charming grad student appears to have his life together, while Lily's on the brink of losing her reputation and her book deal.
Told in present day with glimpses of the past, The Do-Over is a delightfully warm and hopeful story about second chances in life and love, and how the future might not be a straight line, but we still end up exactly where we're supposed to be.
