Since Lila Sacher was orphaned, she lives with her uncle Argus, probably the most brilliant and extravagant inventor to walk the world.
Their travels have taken them to extraordinary places, but Lila is already beginning to yearn for something her uncle can’t seem to offer her, a true home. Perhaps Professor Pedrúsculo Ivinovich, her only living relative next to Uncle Argus, can take her in.
With this hope they set off for St. Petersburg, but once there they discover that this is only the first stop on an adventure that will take them to the other end of the world.
