To avoid extinction, there’s only one hope for the winged inhabitants of the planet Belizair. Come to Earth and claim the perfect, genetically-matched mate, the catch—it has to be done in pairs, a feather-winged Amato must share a lover with a bat-winged Vesti. The stories set in the Fallon Mates series can be read as stand-alones, though like any series, the enjoyment is deepened for having met the characters who overlap from story to story.
