Terry invents a machine that can send him into his own future. Planning on getting rich, he jumps forward five years only to find himself as a woman, on his hands and knees about to be taken by his strapping neighbour.

It is the Siege of Antioch in the First Crusade, and the young squire Richomer is following his master knight’s example in raiding the city after it has fallen. But when he takes a valuable bottle, ignoring a woman’s warning, he is shocked when he opens it and he is instead transformed into an attractive Arabic djinni! The new djinn must grapple with her changed gender, species, and powers as she hopes for a master to let her out.
