Freed from a centuries-long prison, Icarus Morgenth, the last phoenix, finds himself in a world louder and faster than he remembers. His golden tears can scorch stone, and his grief can erupt in fire. But he only wants to breathe, to feel the sun, and perhaps, just perhaps, to find a place where a creature of flame is not feared, but understood. Can the Shadowhunters, who accidentally freed him, earn his trust before his power or his sorrow consume him... or before others discover the ancient being now walking among them?
