Master Cain is an intergalactic bounty hunter who is regularly employed by the king of Arriden to find his regularly runaway son. To assist him, Cain buys a man-dog called Star. But Star turns out to be a eunuch from Earth with fantasies of being a man-dog. Together they set out into the desert to find the prince, capture him, and return him to the capital, Tamzen City. However, the desert holds surprises and threats neither man nor man-dog could have imagined. (M/M)
