Dreamfire

Unlike most seventeen-year-olds, Joshlyn Weaver has a sacred duty, to enter the Dream universe we all share and defeat nightmares. To fail is to release those nightmares into the world, with all the emotional turmoil they cause. But despite Josh's reputation as a dream-walking prodigy, she's haunted by her mistakes. A lapse in judgment and the death of someone she loved has left her doubting. Now she's been assigned an apprentice, a boy whose steady gaze appears to see right through her, and she's almost as afraid of getting close to someone again as she is of getting them killed. Then strangers with impossible powers begin appearing in the Dream and it isn't just Will that Josh has to protect - it's the whole world.
