A split-second decision can change everything…

At the edge of a forest, a husband and wife are driving through the winding lanes. When a song comes on the radio, the song that brought the high-school sweethearts together on a dancefloor forty years ago, they turn to each other. That split second—a stolen glance as memories wash over them—is one of their last. Moments later, their car crashes.

Yet from tragedy, comes hope…

Two strangers lie in hospital, their lives hanging in the balance. After a near-fatal accident, it's a miracle that Zack survived. And with a life-long heart condition, Chloe didn't think she would make it past her twenties.

But that day, Chloe and Zack's lives are saved when they each receive a heart. Gifted a rare second chance, it's up to them not to waste it—to make the most of every moment.

They don't know it, but they are inextricably linked. And until Chloe and Zack find one another—two hearts searching for their missing part—their new lives can never begin…

Will they be able to find each other before it's too late?

An absolutely gripping and heartbreaking tale that will make you reach for the tissues but ultimately leave you with a smile. Fans of Jojo Moyes, Jodi Picoult and Diane Chamberlain will fall head over heels for this unforgettable story about making every second count.
