The Zero Saga

A dystopian science-fiction duology by H.D. Carlton. A parasitic infection has turned the Zolarian colony into cannibalistic monsters, and their leader Ronan is sent to Earth in search of a cure, under orders to wipe out humanity. Beneath Area 51, Zero Alvarado has spent her life training for exactly this kind of invasion. As the two leaders clash, the series blends horror, action and romance across its two books, Hollow and Untainted.
