Mia's at her wit's end. She hasn't had a moment alone since the last attack, and the twins won't let up, the twins aren't the only ones a little too interested in Mia these days. Lorien's new boyfriend, Ashton Wolfe, wants Mia to help him write a book about what happened with Mr. Quillen earlier in the year, but when she agrees, she discovers that might not be all he's after, and he might know a lot more than he let on. Waiting for her before school every day, following her to all her classes, and popping up the second she has a single moment to herself. Even worse, they won't even tell her what's been happening on Flicker Island and why they're so sure she's still in danger.

And Mia and the twins have bigger problems than another nosy journalist, though. Something terrible is simmering on the island, but Mia is determined to see it for herself, anyway. As she meets the strange inhabitants of the island and sees what they can really do, she realizes they might be every bit as dangerous and ruthless as Ian said. Even the mainland doesn't feel so safe anymore.

When she arrives home, Mia starts sharing horrible nightmares with Ian, and she starts to fear they've brought something back with them from the island. As the nightmares become more and more real, Mia and the twins have to figure out who is behind them before the dreams start to leak into reality and destroy them all in this chilling conclusion to the Nightmare Island Series.
