Exit Light — Megan Hart

Tovah Connelly would rather be asleep than awake. Since her accident, she's become a shaper in the dream world, the Ephemeros, where she can manipulate places and people with just a thought. Tovah's friends there, Ben and Spider, encourage Tovah to develop her skills, but the one ability she doesn't want is to control the dreams of others -- it's a power she's wary of, and a responsibility she's not ready for.

Nobody can sleep all the time, though -- not if they want a waking life that bears a semblance of normalcy. And Tovah's waking life is vastly different from her dream life: she's rebuilding and regaining her sanity after nearly losing it in the accident's aftermath.

But when nightmares begin rocking the Ephemeros, Tovah's two worlds begin to collide. As those she cares about are threatened, Tovah may discover that the one responsibility she doesn't want is the only defense she has.
