EMMA + LUKE = DISSAPEAR TO NOWHERE
The first book in the Emma + Luke series stars a boy and a girl of 12 and 11 years of age. Typical school kids, they have no idea of the adventures in store for them when they fall through a portal that transports them to a far-off planet run by a civilization that has been using the Earth to conduct social experiments.

The far-off world that Emma and Luke have stumbled onto is a refuge for civilizations that have escaped the ongoing galactic wars and just one of the vast number of populated galaxies in the Multiverse.
