For her first book, Ms. Greenberg takes us on an imaginary journey to the early days of our home planet. This graphic novel is superbly illustrated and the story, though it takes place mostly in an icy clime, is warm and comfortable. The mythology deals with a boy who is split in three at birth to accommodate three sisters, and though the split entities eventually come together again, the reunited one loses a crucial part of his soul. But there is constant humor throughout: At one point our hero is swallowed by a whale. The whale yells at him "Please stop running or I'll puke you up!" It's also a story of storytelling, and its riches will stay with you for quite a while.
