Finley, Mya, River, and Eli were inseparable as kids, running wild on Alaska’s vast wide-open spaces. Then tragedy struck, and Finley moved to the lower 48. But now it’s Senior year, and Finley’s back in Anchorage. When Mya throws a house party on a snowy Valentine’s Day night, it’s supposed to be a chance for the friends to heal old wounds. But an encounter with a mysterious stranger quickly turns the evening into a nightmare.

As the group scrambles to cover up what they’ve done, the fault lines they’ve grown so good at ignoring begin to crack as the police investigate and the media hounds them. Are they the most vicious teens in America, or deeply misunderstood? Everyone wants to know—even the teens themselves.

Fast-paced and thrillingly tense, THE TRESPASSERS explores guilt, loyalty, and the complex nature of friendship.

Jennifer grew up in Alaska and now divides her time between Northern California and Middle Tennessee with her husband, kids, and more than her fair share of pets. THE TRESPASSERS is her 11th novel.
