Theo, a 17-year-old American backpacker exploring Europe, tries to brush off the odd behavior of the townspeople of Bridgingdale, an obscure English village-until a suspicious fire in the town square reveals the first of the town's many secrets.

At the center of it all is the mysterious and daring 17-year-old Leyna, a Book Keeper with an ancient calling to mend tears between the literary world and reality.

When fantastical monsters and villains start escaping their stories, Leyna insists it is someone else's nefarious doing, but the townspeople refuse to accept this as possible. Only Theo believes her. Together they must work to discover and stop the saboteur before it's too late . . . for both worlds.
