Grey Haven — Lynnie Purcell

Julie Aim knows three things: life is never fair, rules are for people not clever enough to circumvent them, and she's awesome at fighting shades (demons that possess people via their dreams).

When strange attacks begin happening around the school that trains her to fight shades, Grey Haven, Julie is pulled into a plot of betrayal, uncomfortable social encounters, and murder. It's then up to her (re: her ability to circumvent the rules), and her friends to prevent a plot that could destroy the school forever.

‘Grey Haven' is the first book of the Dreamer Chronicles series.
