When a brutal angel army trespasses into the human world, Karou and Akiva must ally their enemy armies against the threat -- and against larger dangers that loom on the horizon in this thrilling conclusion to the Daughter of Smoke & Bone trilogy.

Seventeen-year-old Karou, a lovely, enigmatic art student in a Prague boarding school, carries a sketchbook of hideous, frightening monsters--the chimaerae who form the only family she has ever known.
