The Atlas Paradox by Olivie Blake

As the surviving recruits of a clandestine magical society grapple with the disappearance of one of their own, fragile alliances splinter and power struggles intensify under the guidance—and manipulation—of their enigmatic mentor. Each contestant confronts the moral cost of their increasingly volatile abilities while outside forces close in, secrets surface, and a risky rescue attempt tests the limits of time, loyalty, and truth. Betrayals mount and philosophies collide, propelling them toward a reckoning that could redefine the purpose of their order and the price of knowledge itself.
