Undertown (Futa Apocalypse #2) Mara is starting to settle into her new life with Kathryn, but there's something bothering her. The people around her seem content with their lot, and they're not doing anything to prepare for the future or protect themselves should they need to. They could try to expand Undertown, they could try to find other survivors like her, but they don't. Even Emma doesn't think there's anything they can do, and Mara starts becoming frustrated. It changes when she finds out Madelyn knew her mother and father, and once she discovers everything the other woman knows about her. Madelyn's revelations aren't the only thing rocking Mara's world however, and soon the whole of Undertown will face a scare that will force them to change.
