Meet Maya Subramaniam: thirteen years old, schoolgirl by day, Preferred by night.

Throw in a pair of disapproving parents intent on stopping her forays into an alternate world, a two-metre-tall Watcher who can sense her state of mind, and Lev, her best friend, who could technically be her worst enemy.

Certainly, Maya’s life is quite full, and the last thing she needs is an unpleasant involvement with an ancient conspiracy. But being in possession of a valuable artefact belonging to the renegade Warriors of the Shadow, she has little choice in the matter. The question is, should she believe a two-thousand-year-old jumble of calculations, or follow her instincts and trust her Watcher’s logic?

As events spiral towards a grim climax, Maya, Lev and their Watchers are caught in a deadly race. Will they win? And at what cost?
