One of the most distinctive features of the Quotient Series is its commitment to real geography. Every location referenced in the books is a real place in the world — and most are places Greg has visited himself. For example, this photo was taken on the River Reuss in Lucerne, Switzerland — a scene that appears in The Quantum Contingent.
