Publisher Description

A woman struggling with burnout learns to embrace the unexpected—and the man she enlists to help her—in this new New York Times bestselling romance by Helen Hoang.

When violinist Anna Sun accidentally achieves career success with a viral YouTube video, she finds herself incapacitated and burned out from her attempts to replicate that moment. And when her longtime boyfriend announces he wants an open relationship before making a final commitment, a hurt and angry Anna decides that if he wants an open relationship, then she does, too. Translation: She's going to embark on a string of one-night stands. The more unacceptable the men, the better.

That’s where tattooed, motorcycle-riding Quan Diep comes in. Their first attempt at a one-night stand fails, as does their second, and their third, because being with Quan is more than sex—he accepts Anna on an unconditional level that she herself has just started to understand. However, when tragedy strikes Anna’s family she takes on a role that she is ill-suited for, until the burden of expectations threatens to destroy her. Anna and Quan have to fight for their chance at love, but to do that, they also have to fight for themselves.

Smiling Face with Heart-Eyes“Why did I take so long to read this?????? This book was fantastic!!! I’m not usually one for insta-love, I much prefer slowburn, but Quan and Anna’s relationship was just perfect. Heartwarming, cute, sweet, and funny. But, it was also real, emotional, realistic, and relatable in many ways. It was amazing to see the character growth, too. It was also SUCH a pleasure to read this with my club members!🫶🏻”
