About this book

Atlas knows that stalking a monster into the literal depths of hell is a reckless move, but he is desperate for belonging. When he crosses paths with Bel, a powerful demon, he finds far more than just a job offer. He finds a sanctuary, a family, and an undeniable pull toward the man who rules his heart. For Bel, the scent of his fated mate is an intoxicating revelation that changes everything, prompting him to keep the curious human close as his assistant.

The bond between them is instantaneous and electric, but their underworld romance takes a chaotic turn when they face a biological impossibility. When Bel discovers he is pregnant, the couple is thrust into uncharted territory that challenges the very foundations of their connection. In a realm where such miracles are unheard of, they must rely on the strength of their mate bond to navigate the scrutiny and dangers of hell.

Athena Steller delivers a captivating paranormal romance that blends dark, imaginative world-building with the sweetness of soul-deep devotion. If you crave fated-mates tropes, high-stakes demon lore, and the emotional intensity of Mpreg, this story offers a unique escape into the shadows. Prepare to fall for a love that defies the laws of both heaven and hell.

Curiosity leads to happiness

Running an errand for Lucifers mate leads Bel to the one place he dislikes, the movie theatre. Atlas recognises Bel for who he is and a little bit of stalking ensues as Atlas seeks answers of his own. What Atlas discovers is a world he never imagined. A sweet mpreg story, with meddling found family, humour, spice, nesting and a tease with more interesting characters that you just want to read about. I voluntarily received an arc of this book. )
