To Steal the Queen — Beth Alvarez

If a single thing goes wrong, this heist could be his last.  Even thieves have loyalties, so when Tahl—the legendary Ghost of Orrad—discovers someone has been stealing from the sweet old woman who once offered him shelter, he's determined to set things right. When his personal mission leads to an accidental kidnapping, it draws the attention of Orrad's queen, who has an interesting proposition: a job for the Ghost. Tahl knows it could be a trap, but with a reward that rivals a king's ransom, it might be worth the risk—or it might just get him killed. To Steal the Queen is a full length novel and the final adventure in the Westkings Heist trilogy.
