In the post-apocalyptic future, Wren and his companions prepare for one final battle against his nefarious half-brother and the horde of cybernetic zombies Wren is living in Greenstone under the temporary care of Charles and Mol, and the protection of Chapel. Unable to determine the fate of his mother and those he left behind in Morningside, Wren believes there is nothing left to do but wait for Asher's final blow . . . until a man named Haiku walks into the Samurai McGann, looking for Three.

As Cass and the few who survived the fall of Morningside face overwhelming odds to escape Asher and the Weir, they realize it is impossible . . . until their daring and probably suicidal plan to strike turns out to have surprising results and unexpected discoveries.
