When a wounded woman (with a tail) appears on her doorstep, Nat crash lands at her old job in the emergency room of the city’s last recourse for the otherworldly ill. The personnel are overworked, the facility is underfunded, and all operations must be kept hidden from the public, including Nat’s own family. Some of the staff, like the self-duplicating nurse Lydia Black, are glad to have her back. Others, like Luis Cervantes, a new resident with something to prove (and more to hide), not so much. And who can tell what Dr. Kumasaka, the ghostly head of the department, is thinking? All Nat knows is that the overwhelming need they face every day is enough to keep the truth of why she left St. Lilith’s at bay, at least, for a while. Then a magical plague hits the city, and everything sets to change, for everyone. From the author of bestselling titles for , , and others comes an intense medical drama abound with fairies, trolls, and real human pathos. Collects #1–#4.
