Dr. Aristotle Campbell is a desperate man. His twin brother has been abducted, and Ari will do anything to find him. Forced out of the comfortable solitude of his laboratory, Ari must leave their home world of Britannia and search the farthest reaches of space for his other half. He hastily equips himself with a flawlessly tied cravat, a handful of clues, and his small science vessel. Now, all he needs is a pilot to get him across the Verge, a barrier separating the civilized world from ungoverned space.
