Her dreams have ignited cracks in the universe wide enough for things to slip through--nightmares--and the only way to keep the world from ripping apart at the seams is to find the other Dreamers and wake them too. But Bryn's death has awakened something else--a dark desire in her to give in to the madness that led to the First Dreamer's demise. Roman knows what it's like to give in to the darkness.
