Set in the deep future, Gage is a pilot transporting models for hire between the Jovian moons.  The girls are sold for a year or two doing everything required of them in their contracts.  Gage is a sold man himself, having sold himself to Sleeping Beauty Inc. until he turns 30, but that might be a while as he spends 26 days out of 30 asleep on his ship.  That is until one of the models he transports, Iona, has a contract for him.  Looking over the contract, he can't believe his eyes.  She can't really mean to buy him!
