Dance of Thieves. Mary E. Pearson.

A formidable outlaw family that claims to be the first among nations. 
A son destined to lead, thrust suddenly into power. 
Three fierce young women of the Rahtan, the queen’s premier guard. 
A legendary street thief leading a mission, determined to prove herself. 
A dark street that is a threat to the entire continent. 
When outlaw leader meets reformed thief, a cat-and-mouse game of false moves ensues, bringing them intimately together in a battle that may cost them their lives - and their hearts.
