Ivy and the Meanstalk — Dawn Lairamore

Having saved her kingdom from the dastardly designs of a scheming prince in Ivy's Ever After, fourteen-year-old Princess Ivy and her dragon friend, Elridge, have little time to rest on their laurels, for Ardendale is once again being threatened. It seems that many years ago a magical harp and a hen that laid golden eggs were stolen by a youth named Jack. The rightful owner, a surly giantess who hasn't slept a wink since the thefts, needs her harp back to cure her insomnia. Otherwise Ardendale will suffer an unspeakable fate. So Ivy and Elridge set off on another fairy-tale-inspired adventure--a quest for the magical harp that takes them across the sea, into the fiery depths of a magnificent golden kingdom, and high into the clouds to the top of a vicious man-eating meanstalk.
