The final day approaches. An ancient spell will force Dan to leave the magical world of Inland forever, unless he marries his fairy girlfriend Maggie. That goal is fine with Dan and Maggie—they want to spend their lives together in Inland anyway. But their nemesis, the witch called Sister, has captured Maggie and intends to use their combined power to control and ruin Inland. Dan brings his friends from the regular world to help him defeat Sister and free Maggie. But first they must find them. And Dan has only two full moons until the spell takes effect and he will never see Maggie again. Will Inland twist away from Dan no matter what he does?
