Emma and Eadric have no sooner been turned back into humans (from being frogs) than Emma's mother is in a panic, Aunt Grassina is distracted because her true love has been turned into an otter, and Emma's magic is so out of control she sends herself to the dungeon by mistake. The neighboring kingdom has chosen this moment to attack, and if Emma can't get Grassina to refocus on protecting the kingdom, life as they know it in Greater Greensward will be in peril. From underwater sea monsters to fire-breathing dragons, this witty pair of young friends manage to sweet-talk, cajole, and race their way to victory. But just when everything seems to be working out, disaster strikes, and Emma discovers that magic is not enough — it takes real bravery and a strong new friendship to succeed.
