Dreamside — Graham Joyce

Finally available in America: the debut novel from the author of The Tooth Fairy and Dark Sister

It began as an experiment in college--a seemingly harmless investigation into "lucid dreaming," the ability to control one's dreams.

But they stayed too long on Dreamside, and now, ten years later, the dreams have returned--returned to upend their adult lives. The dreams of youth fade, if you're lucky. If not, they can consume you . . . and will.
