Aideen killed her mother and her childhood friend. At least that’s what she believes.

Death follows her like a curse, and with every loss, her gut whispers the same truth—it’s her fault. Determined to keep anyone else from dying, Aideen plans to escape to the West Coast for college and leave her haunted past behind.

But when her best friend Emily goes missing, running is no longer an option.

The police offer nothing but dead ends, so Aideen takes the search into her own hands, joined by the one boy she’s spent years keeping at a safe distance.

Terrified of losing him, too, Aideen follows a trail of clues Emily left behind … straight into a clandestine world of monsters. Stalked by glowing symbols that have shadowed her dreams for years, and hunted by legendary creatures for reasons she doesn’t understand, Aideen is thrust into a supernatural war she never asked for.

To save her friend, Aideen partners with a ruthless vampire and an unpredictable shifter, and must face the horrifying possibility that the thing she’s been running from isn’t chasing her at all. It’s inside her.
