Sure, 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, her two best friends are anything but average. Both of them are famous for their adventures. Jasper Dash, Boy Technonaut, invents gadgets; Katie Mulligan spends her spare 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.
