Remy LeBeau, a suave and mysterious mutant with the ability to charge objects with explosive energy, has spent most of his life in the shadows as a master thief in New Orleans. Raised by the Thieves Guild, Remy tries to walk a fine line between loyalty to his criminal family and his own moral code. But when a high-stakes job goes wrong, Gambit becomes the target of both the rival Assassins Guild and a shadowy government agency hunting mutants. As Remy uncovers a conspiracy involving stolen mutant DNA and an ancient artifact that could amplify mutant powers, he’s forced to confront his past and accept his role in a war brewing between mutants and humanity. Along the way, he crosses paths with Belladonna Boudreaux, his former lover and now a deadly assassin; Mister Sinister, the genetic manipulator with a twisted interest in Remy’s unique mutation; and a young runaway mutant who reminds him of the good he’s still capable of. Torn between his roguish instincts and a growing sense of responsibility, Gambit must decide whether to remain a thief—or become something more.
