In the shadowed heart of Ravenshire, where ancient forces stir beneath gothic spires, Thalia Ravencroft stands as humanity's last defense against the darkness. As the city's Sentinel, she's sworn to banish demons back to their realm-until she encounters one unlike any other.

Malekith Thorne has walked among humans for centuries, a fallen angel trapped in mortal form. When dimensional barriers begin to crumble, these sworn enemies are forced into an alliance that challenges everything they believe.

As they race to prevent catastrophe, their forbidden attraction ignites into a passion that defies the laws of both their worlds. Each touch, each shared secret, draws them closer to a truth that could either save both realms or condemn them forever.

Some bonds transcend duty. Some desires defy destiny. Some unions remake reality itself.
