Shadow Brigade Series by Robyn Wideman

Rogue is a cantankerous warrior, a bandit, and a brawler. He only wants to be left alone and occasionally rob the king who once betrayed him. But when assassins try to kill a young woman, Rogue gets involved. Now he is involved in a dangerous plot, and to protect the girl he must save a kingdom, a kingdom he once almost destroyed.

A warrior comes home. Mendris Fox, infamous sword-for-hire, returns home to search for the man behind the attacks on him and Princess Jasmine Grant, only to find that the assassination plot was only a small part of the puzzle. Dragons have returned to the land of man, and the Dragonian priests who worship the beasts have been plotting to enslave nations, including Mendris' home... moreA warrior comes home.
