Call Down the Hawk (the Dreamer Trilogy, Book 1) by Maggie Stiefvater
From the #1 New York Times bestselling author of The Raven Boys, a mesmerizing story of dreams and desires, death and destiny.
The dreamers walk among us . . . and so do the dreamed. Those who dream cannot stop dreaming – they can only try to control it. Those who are dreamed cannot have their own lives – they will sleep forever if their dreamers die.
And then there are those who are drawn to the dreamers. To use them. To trap them. To kill them before their dreams destroy us all.
