The Trigon Rituals  - Angelia Whiting Tren and Rjant are looking for the mate who happens to be Alea from Earth. After a pretty boring beginning once they meet up with Alea it gets much better. Someone forces her into a compromising position which has her questioning her morals, but they work through it. Very good book. 3.5 stars. I'm planning on reading the rest of the series.
