The Painted Man / The Warded Man, by Peter V. Brett
Somehow I acquired two free copies of this book with different titles. It's not bad first-book-of-a-fantasy-series; the world where humans are besieged nightly by deadly demons, and must ward them off with hastily-drawn magical sigils, is well realised, and the brutality of the human society conveyed effectively. Didn;t grab me sufficiently to make me want to look for the next in the series; my bar for big fantasy series is quite high.
