A mysterious and magical "unicorn girl" is saved from the prisons of scientists and bureaucrats, only to find herself threatened by a man known as "the Piper," whose trade is child slave labor.

The future of an entire species rests on the delicate shoulders of a tiny baby who was set adrift in a lifepod to save her from the vicious hands of Khlevii warriors. Her rescuers, three bachelor asteroid miners, marvel at the unusual child's astonishing growth rate and superior intelligence, naming her Acorna for her other-worldly silvery mane of hair and horn-like bump in the middle of her forehead.

Enchanting though she is, young Acorna's unusual talents capture the attention of some unsavory intergalactic inhabitants who are determined to twist her powers for their own gain. But as Acorna gains control over her powers she matures into a worthy contender in the interspatial adventures that pursue her in her desperate search for her People and their world.
