Grudgebearer – J.F. Lewis

I enjoyed reading this book, but decided not to read the sequel. The story has a lot going for it, but the characters are wafer-thin, and that is allowed to drive the plot. Kholster leads a race of super-soldiers - there are a lot of them and they are virtually immortal - who cannot survive breaking an oath. When his people broke free of their enslavers, he promised to let the enslavers live, as long as they didn’t do something stupid and petty. Dolvek is a prince of the former enslavers - and he does something stupid and petty. Meanwhile a major inter-species war is breaking out because the gods are playing a game - and they’re that petty too.
