Alpha Hades by Paulina Vasquez

Some things can’t be mended. Born into the shifter world he hates, Alpha Hades finds his destiny on the same road used to avoid it. The air of danger that surrounds him is felt by humans and werewolves alike. He’s both a beast and a genius.
With a Bratva Prince at his side, Hades and Kazimir find themselves thriving in the shadows of the underworld, but the Moon Goddess seems to have other plans for them. This bad boy never wanted a mate but now that he’s found her, he wants to possess her. Odessa Theodorus may just be his redemption, though it’s not redemption he seeks but retribution. From cage fights in Moscow to the shores of Cyprus, all roads lead back home to Greece.

(Alpha Hades is book #1 in The Alpha Chronicles which are stand-alone novels.)
