New York Times bestselling author Christina Lauren returns with an unforgettable romance in which a fateful accident erases a troubled marriage from memory—and a scientific breakthrough gives love one extraordinary do-over.

Three years ago, scientist Emery Finch did something completely out of character: She got married. To Luca—the impossibly charming landscaper she met on one blistering night in Vegas who made her laugh, made her dance, made her feel. But now, Emery is consumed by her top research, missing dinners, forgetting anniversaries, and promising herself Luca will understand once her cutting-edge discoveries come to light. Until the unthinkable happens: A tragic accident takes Luca from her. Desperate not to lose him, Emery breaks every rule, using the classified technology she’s developed to bring him back to life. And Luca would probably thank her for it, if only he could remember her. Their first kiss, their Sunny Sundays at the beach, the life they built together...all of it is gone. It may be a miracle of science, but for Emery it’s her one shot at a second chance. And this time, she won’t waste it—because true love is always worth reviving.
