Dead of Eve: Trilogy of Eve Book 1 by Pam Godwin

A virus devastates humanity. Few men survive. The rest are monsters. The women are dead, except Evie.

Through a quirk in her genetics, she survives. When her physiology begins to evolve, she must come to terms with what she is and accept her role in finding a cure.

The mutated hunt her. The men brutalize her…except three. Cryptic warrior, contrite lover, caring enemy; they are fiercely protective of the last living woman, but divided in their own agendas. Can they come together to protect the only hope for humanity?

Evie must survive.
