Guardians of the Shimmer: Dreamtime

Guardians of the Shimmer: DreamTime is a young adult novel featuring Cole and Lily Fletcher, a couple of Kiwi kids who are on their way home from a camping trip with their parents when an accident catapults them into DreamTime, the place where people's dreams exist. As if that isn't enough of a shock, they then discover that their parents are part of the Blue Ghost, long time Guardians of the shimmery barrier that separates reality from dreams. The Guardians serve to protect sleepers, ensuring that they return safely to their RealTime selves. The only problem is the VELI, dark and sinister monsters of nightmare, who are no longer prepared to dwell in the shadows. Well, that, and the fact that nobody seems to want to tell Cole and Lily what's going on!
