The youngest of King Triton’s daughters, and the most defiant, Ariel longs to find out more about the world beyond the sea, and while visiting the surface, falls for the dashing Prince Eric. With mermaids forbidden to interact with humans, Ariel makes a deal with the evil sea witch, Ursula, which gives her a chance to experience life on land, but ultimately places her life – and her father’s crown – in jeopardy.

Sixteen-year-old Ryan Delaney has won a scholarship, but it's not a full one, so he needs a summer job to pay for his university expenses. And although he's not eighteen, he can't swim, and has never been to camp, he manages to get a job as a camp couselor. But his mother makes him take his younger brother, Sullivan, with him to camp, since she can't look after him while she's working. But camp turns out to be harder than both Ryan and Sullivan thought it would be; and as they fight their battles, they learn about each other, themselves, and what they can do together.
