On an ordinary day in the countryside, Philemon falls into a well on his father’s farm and lands . . . on the Atlantic Ocean — literally on an A-shaped island complete with unicorns, centaurs, and exploding clocks. He begins a wild and whimsical journey home through a fantasy world as original as Alice’s Wonderland, as richly imagined as Little Nemo’s Slumberland, and as exciting to explore as Oz.
