Flesh and Fire Series by Jennifer L. Armentrout

This is Fine Print First Copy - Similar to Original but not Original.

Before there was Poppy and Casteel… there was Sera and Nyktos.

Set in the same world as the Blood and Ash series, the Flesh and Fire series is its prequel saga, exploring the origins of the gods, the realms, and the prophecy that sets everything in motion. At the center is Seraphena Mierel — a powerful mortal with a fate she doesn’t want — and Nyktos, the terrifying yet magnetic Primal of Death, who is far more than the monster she expected.

Bound by duty and destiny, their journey is one of deadly secrets, divine war, betrayal, and an all-consuming love that could break the realms.
