Nightmares - The Dreamer Chronicles, #5

Julie's life in Mexico is far from peaceful as she learns new ways to kill shades, but it's everything she had hoped to find when she left Carrie, Tommy, and Ben behind at Grey Haven. Under the careful guidance of her teacher, Veronique, Julie has come in to her own as a dreamer. More, she's beginning to understand who she is and what she wants out of life. But Grey Haven comes calling in its usual chaotic fashion four months after her departure.
With possessions, explosions, murders, torture, and everyone out to get her, Julie faces the most difficult fight of her life. It'll take more than willpower, determination, and luck to face her demons. It'll take family. Nightmares is the fifth book in The Dreamer Chronicles.
