"Fitting in can be hard, especially when you're as small as Ember, a tiny boy living alone in a city of giants. But Ember's luck changes when he meets Lua, a kindly sea turtle, who escorts him across the ocean to a school for little creatures on a wondrous island...As he struggles to adapt to this new world, Ember finds himself at the heart of an otherworldly mystery, facing a strange monster from the deep that threatens everything he holds dear" -- Provided by publisher.
