Seven years ago

Fifteen-year-old Raffety freaks out the moment he arrives at summer camp. Something isn’t right about the place, parents, kids and the counsellors. The only good thing is Jonah—and their first kiss.
Trouble is Jonah’s middle name. He can’t just ignore that Raffety clearly doesn’t belong at the camp, and risks everything to help him escape, even their budding friendship.
Jonah’s actions have damaging repercussions for both boys. Raffety returns to a very different world than the one he left, one where his mum is terrified of strangers who insist they’re pack. As for Jonah, his father decrees he’s gone too far. His memories of Raffety are wiped and Jonah’s exiled to Faerieland.

Present Day

Breaking cover for his mum’s funeral lands Raffety back in the claws of a pack that never stopped searching for him. The alpha is claiming Raffety’s an omega, and prime breeding material. Erm, no way. Raffety would rather eat his own eyeballs. He needs to figure out a way to escape—and quick.
Indentured to Paranormal Resolutions for his sins, which are many, Jonah’s ordered to extract a mark from the clutches of a pack of werewolves. The mission fills him with dread: the wolves know he stole their gold and if they catch him, they’ll eat his guts, with or without ketchup―gulp! But defying his boss isn’t an option. Not if Jonah wants to live.
Is it chance that Jonah and Raffety end up in the same trap, or is it more? Could fate be giving them both a helping hand, or have they just landed in the worst trouble of their lives?
