The Ghost in Exile:

A Korthlundian Kronicle

The Ghost is going to hell. Not even the goddess can forgive his sins: assassin, oath-breaker, traitor (an affair with the queen earned him that title). No one can ever learn the princess is his daughter. To keep this secret, he flees to the land that turned him from a simple stable groom into an infamous killer.

His mission now? To find evildoers and take them to hell with him. But when an impulsive act of heroism saddles him with a damsel who refuses to be distressed, her resilience forces him to questions why he really ran from his daughter.
