Publisher's Synopsis
When a boy and girl wake up within a stone circle, their minds are blank. They don't know where they are, where they're from or even who they are. Before these questions can be answered they find themselves about to be sacrificed by a Bronze Age tribe. Then the mysterious Foreseer arrives and saves them. He tells them that before they can return home to their own time, they have to steal an artefact from the vicious Beaker Tribe and restore the stone circle to its former glory.
