From the publisher:
In her first hardcover, collecting tales from DETECTIVE COMICS #854-860, Batwoman battles a madwoman known only as Alice, inspired by Alice in Wonderland, who sees her life as a fairy tale and everyone around her as expendable! Batwoman must stop Alice from unleashing a toxic death cloud over all of Gotham City -- but Alice has more up her sleeve than just poison, and Batwoman's life will never ever be the same.
