All Cassie wants is to get some solid ground under her following the shock of her parents' divorce. So when she learns of her mom's plans to take Cass and her brother, Drew, on a four-month sailing trip from Oregon to Mexico, she's stunned. There is absolutely nothing solid about the Pacific Ocean. Cassie is furious. And nervous. It's been hard enough keeping Drew sheltered from what Cassie knows about their mother's role in breaking their family apart, but living in such close quarters threatens to push her anger past its tipping point. Enter Jonah, a whip-smart deckhand who's as gorgeous as he is flirtatious. Cassie tries to keep him at a distance, but the more time they spend together -- wandering San Francisco, riding beachside roller coasters, and exploring the California coastline -- the harder it is to fight the attraction. Cassie wants to let herself go, but her parents' split has left her feeling adrift in a sea of questions she can't even begin to answer. Can she forgive her mom? Will home ever feel the same? Should she take a chance on Jonah? With life's unpredictable tides working against her, Cassie must decide whether to swim against them...or dive right in.
