Irfan Mirza is the ultimate killing machine. Kidnapped as a child and forced to train to become an elite gun for hire at an orphanage, he is now a ruthless freelance mercenary.

In a wealthy Middle Eastern kingdom, despotic King Nimir is determined to quash all dissidents calling for free elections. Billionaires, clerics, influencers, and journalists who dared challenge King Nimir's regime have vanished without a trace. The most recent person Nimir has had "disappeared" is Renata Bardales, a trained fighter raised alongside Mirza--his sister, of sorts.

Now things are personal, and Irfan Mirza doesn't like it when things get personal.

Assembling a ragtag team of specialists, Mirza sets off on a wild rescue mission, determined to save his sister from a medieval fortress that has now been transformed into a heavily fortified blacksite. The prison is surrounded by endless stretches of uninhabited sand, making it difficult to approach and impossible to escape from.

The Palace of Sinners and Saints is a heart-pounding page-turner, perfect for fans of Lee Child and his Jack Reacher series, where courage and loyalty reign and anyone who wants freedom must pay a price.
