The Darkness Within by Alexi Ferreira

In a world where demons fight to protect humanity, Blade, the stoic leader of the Demon Elite Death Squad, never thought he’d fall for a human. But then he met Rayne, a fierce, independent teacher who storms into his life and turns everything upside down. Their connection? Instant and electric.
When demons find their mate, they go all in. Blade is no exception. He’s protective, possessive, and will stop at nothing to keep Rayne safe. But Rayne’s no damsel in distress. She’s determined to stand by his side, even as the rogue demon Rake threatens to tear their world apart.
Together, they face danger, passion, and an unbreakable bond that neither saw coming. In a world of shadows, Blade and Rayne’s love is the ultimate light—powerful, raw, and ready to take on anything.

A journey where love meets danger, and every heartbeat counts.
