Some nightmares you can wake from. Others follow you home.

Julie Aim is anything but fine. Just don't ask her to admit it.

Sully's betrayal left cracks she can't patch, and the dreamworld isn't giving her time to heal. There are too many people who need saving. And too many emotions she'd rather repress.

When a new Shade arrives in town—one that possesses the living and turns them into sleepwalking killers—Julie knows she has to stop it before more people die.

The problem? Her judgment's slipping, her impulsiveness is skyrocketing, and every reckless choice she makes inside a dream has consequences that spill into the real world. Permanent ones.

It doesn't help that the Shade can possess anyone, in a way no one's ever seen before. Anyone and everyone could be a threat. And that threat knows her name.

As the boundary between sleep and reality unravels, the ghosts of old enemies return, dragging new horrors with them.

Some nightmares don't stay buried—and neither do the people who caused them.

Dark, fast-paced, and razor-edged with wit, Sleepwalkers drags Grey Haven's dreamers into their most dangerous mission yet—where survival means facing the horrors they've been running from, and the girl who saves everyone else might not be able to save herself.
