In the first intallment of National Book Award winner M.T. Anderson's Pals in Peril series, a madman has unleashed an army of stilt-walking, laser-beaming, thoroughly angry whales upon the world! Luckily, Jasper Dash and his friends Katie Mulligan and Lily Gefelty are around to save the day.

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.
