The Lies of Locke Lamora (The Gentleman Bastard Sequence) by Scott Lynch

Fantasy meets crime caper in the first book of a landmark, enduringly popular epic series about a roguish group of conmen, which George R. R. Martin has called “fresh, original, and engrossing . . . gorgeously realized.”

An orphan’s life is harsh—and often short—in the mysterious island city of Camorr. But young Locke Lamora dodges relentless danger, becoming a thief under the tutelage of a gifted con artist. As leader of the band of light-fingered brothers known as the Gentlemen Bastards, Locke is soon infamous, fooling even the underworld’s most feared ruler. But in the shadows lurks someone still more ambitious and deadly. Faced with a bloody coup that threatens to destroy everyone and everything that holds meaning in his mercenary life, Locke vows to beat the enemy at his own brutal game—or die trying.
