"On Mystique Island, Christmas isn't just strange—it's deadly."

This holiday season, Mystique Island is proving to be stranger—and deadlier—than ever. Izzy Cooper finally stumbles upon a clue to her grandmother's whereabouts, but with chaos erupting at every turn, acting on it might be impossible.

For starters, her witchy, redheaded sister has cast a spell gone wrong, leaving a poor local man with hands redder than a boiled lobster. If that weren't enough, a string of grave robberies has the town on edge, and fresh body parts are mysteriously appearing in dumpsters.

Things take an even darker turn when a naked and disoriented Elias shows up at the Atypical Crimes Management Unit office. Izzy's feelings for him are already complicated, and now she has no idea how to handle the situation—or him.

But the real kicker? The island's locals are acting... off. They look the same, but they're nothing like themselves—especially her Uncle Aaron. Something sinister is afoot.

And just when she thinks it couldn't get any weirder, Izzy receives an old letter postmarked 1882. Whatever's inside might hold the key to unraveling the madness—or it might lead to an even greater mystery.

On Mystique Island, the holidays aren't just festive—they're downright deadly.
