Jem Moran has a reputation to prove and a secret to protect. The prestigious world simulation program seems the answer to both her problems, but only if she can succeed in spite of her partner, Kir Davos, and the uncooperative human beings who populate her planet. From the Great Extinction to the Renaissance, from world wars to intergalactic treaties, Jem's conflict with Kir will shape Earth's history, and their opposing management styles will either save or doom our planet. Either way, you finally have someone to blame for the shape our world is in.
