The Killing Jar — Jennifer Bosworth

"I try not to think about it, what I did to that boy."

Seventeen-year-old Kenna Marsden has a secret.

She's haunted by a violent tragedy she can't explain. Kenna's past has kept people-even her own mother-at a distance for years. Just when she finds a friend who loves her and life begins to improve, she's plunged into a new nightmare: her mom and twin sister are attacked, and the dark powers Kenna has struggled to suppress awaken with a vengeance.

On the heels of the assault, Kenna is exiled to a nearby commune, known as Eclipse, to live with a relative she never knew she had. There, she discovers an extraordinary new way of life as she learns who she really is, and the wonders she's capable of. For the first time, she starts to feel like she belongs somewhere; that her terrible secret makes her beautiful and strong, not dangerous. But the longer she stays at Eclipse, the more she senses there is something menacing lurking underneath its idyllic veneer. And she begins to suspect that her new family may have sinister plans for her...
