A POPSUGAR BEST BOOK OF THE YEAR In the vibrant city-state of Castellane, the richest of nobles and the most debauched of criminals have one thing in common: the constant search for wealth, power, and the next hedonistic thrill. Kel is an orphan, stolen from the life he knew to become the Sword Catcher-the body double of a royal heir, Prince Conor Aurelian. He and Conor are as close as brothers, but his destiny is to die for Conor. No other future is possible. Lin Caster is a physician from a small community whose members still possess magical abilities. But despite her skills, she cannot heal her best friend without access to forbidden knowledge. After a failed assassination attempt brings Lin and Kel together, they are drawn into the web of the mysterious Ragpicker King, the ruler of Castellane´s criminal underworld. But as long-kept secrets begin to unravel and forbidden attractions arise, they must ask themselves: Is knowledge worth the price of betrayal? And will their discoveries plunge their nation into war-and the world into chaos?
