What sort of madman would unleash an army of stilt-walking, laser-beaming, thoroughly angry whales upon the world? Who cares! All that matters is that his dastardly plan be foiled. Lucky for Lily Gefelty, her two best friends are the intrepid stars of their own middle-grade series novels: Jasper Dash (better know as the Boy Technonaut) and Katie Mulligan (beloved by millions as the heroine of the Horror Hollow series). It's going to take all their smarts to stop this insane, inane plot from succeeding.
