An otherworldly middle grade story perfect for fans of A Wrinkle in Time and Stranger Things from the author of the Very Nearly Honorable League of Pirates series and the Agatha Award nominee The World´s Greatest Detective. What begins as a rather unremarkable Tuesday quickly turns to disaster when Lucy, the Gatekeeper´s deputy, discovers that her boss has vanished and the door connecting Lucy´s world to the next world over is broken--and it all might be Lucy´s fault. To save the Gatekeeper and set things right, Lucy must break the rules for the first time ever and journey with an otherworldly boy, a suspiciously sneaky girl, and a crew of magical bees into the seven worlds beyond her own. But Lucy isn´t the only one breaking the rules. As dangers gather around her, she learns she´s up against a sinister force that´s playing with the delicate fabric of time and space, no matter what the deadly costs or consequences. Lucy´s never had to save the world before--and now, somehow, she´s got to find a way to save eight of them.
