Calliope Xander doesn't side with anybody. Many years of stealing from the famous thief guilds of Kiern has taught her that. She works alone and she likes it that way.

Against her will, she is joined by Reo Blazes, a haughty and talented Valor looking for freedom. They'll have to work together to finish the mission, but at what cost?
