From the #1 New York Times bestselling author of Say You'll Remember Me comes a beautiful, compelling novel that revels in laughter, friendship, and the messy choices life can throw our way.

In everyone’s life, there’s a split-second decision that can change everything...

For Larissa, it came when choosing which guy to ride home with after a concert. That night, she had no idea she’d met the perfect man. She and Chris are great together, co-parenting a slightly unhinged rescue Yorkie, sharing their favorite books, and judging bread (pumpernickel for the win!). For the first time amid all her side hustles to scrape by, things finally feel easy.

But Chris isn't the one who drove Larissa home all those months ago—Chris is her boyfriend's best friend. All Chris wants is for Larissa to be happy. Standing by on the sidelines is slowly killing him, but making a move would destroy someone else. And he’s just not that guy.
