Lily Gefelty is just an average twelve-year-old girl. But her dad—a normal-enough seeming guy—just so happens to work for an evil genius who plans to unleash an army of extremely cranky, stilt-walking, laser-beam-eyed whales upon the world.

Lucky for Lily Gefelty, her two best friends anything but average. Both of them are famous for their adventures. Jasper Dash, Boy Technonaut, invents gadgets; Katie Mulligan spends her srape time fighting off zombies and were-goats. Surely they'll know what to do. And if they don't? Then it will be up to Lily—average, everyday Lily—to come up with a plan.
