Cethe by Becca Abbott
This book kept me on edge until the very end. It's a hard journey, full of violence and magic. And love. Eventually.
The love story of this book begins in the most non-romantic way: a rape. Stefn, the human protagonist, has the Blood. It's not really explained what this means or why this happens, we later learn that through sex he can give to naragi, a supposedly extinct race of Dark mages, the energy they need to perform their spells. Michael belongs to a family of witches, but he's more powerful than everyone else and he needs to bond with Stefn to expand his powers. Stefn doesn't agree to the bond in the first place, of course, and he resists Michael a few times.
warning : it has a complex story building and intense plot....
i hope you would enjoy it .
