Branded by Fire - Nalini Singh
I liked the strong heroine and the ending was good (an element in there that I didn't expect -- no spoilers -- but enjoyed). The conflict in this series is strong, drawing from the very foundation of the world Nalini Singh has created. But in this novel, I felt the characters' conflict was just as powerful and not simply a reflection of the wider conflict in the world. Questions of loyalty fascinate me and are well handled in Mercy and Riley's story.
