Compatibility: A love story that defies species and gender, seeking justice against true evil.

Some bonds defy biology. Some loves rewrite destiny. When shy Ellis loses a Halloween bet, he never imagined it would change his life forever. Dressed as "Ellisa," he catches the attention of Ki'Drena-Taz, an alien anthropologist whose people are facing extinction. Against all probability, Taz's compatibility scanner identifies Ellis as his perfect Mate. There's only one problem. Ellis is not just human, but male. Unbound by human gender norms, Taz offers transformation: becoming Ki'Drena-Ellisa, the first human-Tactorian hybrid female. Ellis must decide whether to leave behind everything he has ever known for the one person who truly understands him. But love has a price. When Taz and Ellisa risk everything to rescue a victim from a forced Mate-claiming, they breach one of Tactoria's highest laws. Imprisoned and brought before a High Court in a society where females have no voice and powerful males control justice, they face impossible odds. Yet the greatest threat to that world is not their dwindling female population and declining birth rate; it is a woman from Earth who refuses to accept that her voice should remain silent. As Ellisa challenges centuries of tradition, prejudice and abuse, her act of courage begins to expose the cracks in a civilisation built on unquestioned power. What starts as a fight for survival may plant the seed that will alter a patriarchal society forever.
