Harper Kingsley has the perfect life until her brother, Braydon, commits suicide. After his death, Harper returns to North Star, a sailing camp on Whidbey Island where she and Braydon spent eight summers together. Joining her are her three best friends who are ready to rule Senior Hill. Harper just wants to escape to the only place she feels is truly magical.

At North Star, Harper tries to forget her reality, but it's impossible because she comes face-to-face with her brother at a hidden bench in the garden. Is it really him or just her imagination? She knows Braydon is dead. Why is appearing in front of her? Scared at first, Harper rejects his presence, but once he explains that she is the one who brought him back, she wants to hear him out.

Harper chooses to keep these encounters to herself. Who would believe her anyway? It's Jeremy Miller, the camp's ultimate heartthrob and Piper's ex, to whom she will eventually reveal her secret. And he has a secret of his own. Their camp romance turns Harper's friends against her, giving her one more thing to juggle this summer at North Star.
