Cass thought spending a month at a beachside hideaway relaxing and collecting shells would be the perfect escape to finish her novel. When she meets the dark and brooding and much younger Jonah, who's staying next door, her book becomes the last thing on her mind.

Jonah would rather stay home alone than go on vacation with his brother and their friends, but does his best to tolerate the situation after being convinced to go. But when he sees the beauty next door, he cant avoid his attraction.

Together, they break all the rules, but will Cass be able to bring Jonah out of his shell forever, or will he leave her with only the crash of the surf to keep her company?
