Eden Moore - Not Flesh Nor Feathers by Cherie Priest
A devastating storm swells the Tennessee River to dam-breaking levels on the eve of Eden's planned move into a new riverside apartment complex. With the gushing waters comes a tide of corpses, animated and organized by a malignant force with an inscrutable purpose. Reluctant medium Eden may be the only one who can dissuade the zombie army from adding hundreds to their ghastly ranks.
