In the perpetual twilight of Vesper, thief Tristan Abrascal survives through wit and a goddess's capricious favor—until one fateful night shatters everything. His mentor's desperate offer becomes his salvation: a chance for vengeance against the infanzones who've ruled his life. Across the world, Angharad Tredegar flees assassination and ruin, her family slaughtered, her nobility stripped away. Yet survival alone won't suffice; she craves blood revenge. Their paths converge at the Watch, but desperate souls like them must earn entry through trial. The Dominion of Lost Things awaits—an isle where many enter each year, few return. When four emerge victorious, they enroll together at the infamous Scholomance, forming a cabal bound by necessity. Yet no sanctuary exists here. Angharad faces temptations as deadly as the stories warned. Tristan uncovers conspiracies: mysterious abductors, vanishing classrooms, conversations with the dead. Maryam Khaimov battles her own fractured reality, uncertain if madness claims her or something wears her face. Song Ren shoulders the burden of unity, defending against rival cabals and the relentless enemies her companions attract—determined to restore her family's honor before their disgrace consumes them entirely. Beyond Scholomance's walls looms the Asphodel Rectorate: a decaying empire rotting from within, harboring horrors where monsters may be the least threat. As the four chase shadows and untangle webs of treachery, one question lingers: is betrayal ever justified when the reasons run deepest?
