When Joanna Whitman's famous ex-husband dies in a car accident, she doesn't know what to feel. Their dysfunctional marriage held more painful secrets than she cares to remember. But when she discovers that the young woman with him in the crash is pregnant, Joanna feels compelled to act, knowing exactly how brutal the media spotlight will be on celebrity chef Cliff Whitman's ex-wife and his mysterious female friend.

Ashley Blake can't believe it when Joanna shows up in her hospital room and suggests they hide away at her beach house on a sleepy stretch of California coast. Joanna should be hating her, not helping her. But alone and pregnant, Ashley can't turn down Joanna's offer. Yet she knows that if Joanna ever found out the real reason Ashley was in that car, their tentative bond would shatter instantly.

Joanna's only goal for the summer is privacy, but her return causes major waves in the local community, especially for the man she left behind years ago. All Ashley wants is space to plan for her and her baby's future, and to avoid causing any trouble for Joanna. But as secrets spill out under the hot summer sun, this unlikely friendship is about to be put to the test.
