Falling to sleep has never been so tiring. Sleep climbers Jayden, Connor and Max meet in a strange, moonlit dream land where the only way to 'fall' asleep is to climb. The climbing is not so simple, though. The mountain is full of night-time animals and things that could only exist in a dream world. Jayden, a brash, assertive girl, battles her own demons while joining forces with Connor, a calm, intuitive young man, and Max, a young teenager trying to be a man in a boy's body. Together, they climb their way up the mountain but their many adventures are interrupted by Richard Hatemore, an evil, sickly-looking boy who will stop at nothing to prevent them from reaching their goal. As the sleep climbers move closer to the top, they begin to work as a team and ultimately, face their greatest challenge together.
