Serpent's Reach (Alliance-Union Universe)

I liked this book set in a rich and complicated universe. I especially liked the way the majat are portrayed and how Raen interacts with them.

Within the Constellation of the Serpent, out of bounds to all spacefarers, humans live among the insect-like aliens--and one of them, a woman named Paen, is bent on a revenge that will tear apart the truce between human and alien. "Brisk pacing . . . and genuinely brilliant world-building."--ALA Booklist. Reissue.
