The Last Hunt weaves together all the strands of the great clash between the Hunters and the unicorns. As the Hunters invade Luster, bent on the extermination of the unicorns, the unicorns rally to defend themselves. To do so, they will be forced to make peace with their intimate enemies, the delvers. Even worse, the Hunters may not be the greatest danger; Luster itself is beginning to collapse from the damage done to the great world tree where Beloved tore a whole between the worlds. Preventing that collapse will require Cara — reunited at last with her mother and father — to discover the secret of how and why Luster was originally created. But first she must confront her own ancestor, the fierce and wily Beloved!
