From New York Times best-selling author Jill Shalvis comes a friends-to-frenemies-to-sisters story....

Add in a few secrets. Shake. Stir. Then listen on a lazy summer day at the beach.

Brynn Turner desperately wishes she had it together, but her personal life is like a ping-pong match that’s left her scared and hurt after so many attempts to get it right. In search of a place to lick her wounds and get a fresh start, she heads back home to Wildstone.

And then there’s Kinsey Davis who, after battling serious health issues her entire 29 years of life, is tired of hoping for...well, anything. She's fierce, tough, and she’s keeping more than one bombshell of a secret from Brynn - her longtime frenemy.

But then Brynn runs into Kinsey's best friend, Eli, renewing her childhood crush. The good news: He’s still easy-going and funny and sexy as hell. The bad news: when he gets her to agree to a summer-time deal to trust him to do right by her, no matter what, she never dreams it’ll result in finding a piece of herself she didn’t even know was missing. She could have real connections, possibly love, and a future - if she can only learn to let go of the past.

As the long days of summer wind down, the three of them must discover if forgiveness is enough to grasp the unconditional love that’s right in front of them.
