Amber Nicholls, Lachlan McCarthy, and Raffaele Wright would normally have absolutely nothing in common. But growing up as foster kids in Teddy Penhaligon's seaside home has forged a bond tighter than glue. Each one has messes in life to deal with, but when they get the news that Teddy's met someone while on vacation, they'll do anything to protect him from a presumed gold-digger—even if they have to save him from himself first. But how can they guide their foster father when they can barely get a grip on their own lives? It's all a madcap jumble as secrets are shared, hearts are changed, and a single summer becomes a season of endless possibility.
