Luke Hartwell's Nathan's Story is a powerful follow-up to his Atom Heart John Beloved. Hartwell has taken Keith Hale's novella Space as the vehicle to introduce an attractive new character, Harper, to the story of Nathan and John. Hartwell intertwines the story of Nathan and Harper with the story of Nathan and John while avoiding a rehash of old information from Atom Heart John Beloved. Like the first book, Nathan's Story makes readers think, covers some controversial ground, can produce tears, and will bring plenty of smiles.
