Can a pond be an ocean?
This isn't the best that Gaiman's ever written, but it's still filled with his delightful prose and vivid imagination. The boy who is the POV character is more of a witness to the events around him, even while he's the unwitting reason for many of them. Leti, her mom and grandmother are as mysterious as they are fascinating. Since the boy isn't really given many answers, a lot goes unresolved or hinted at, but it's the adventure that this boy goes through that matters.
Neil Gaiman narrated this and I could honestly listen to him read the telephone book, so full marks for the narration.
