Alexion is the judge, jury and executioner of Dark-Hunters who break the golden rule -- do not kill humans. Dark- Hunters are the immortal defenders of humanity. When Dark- Hunters break the rule, Acheron sends Alexion to destroy them. Apollites die at 27 years unless they turn Daimon and drink the blood of humans and steal their souls. The Dark- Hunters' mission is to protect humans from these evil Daimons.

A Dark-Hunter in Mississippi crosses the line and kills a human, while another Dark-Hunter, Kyros, is trying to turn all the Dark-Hunters in Mississippi against Acheron, the one who saved them from death, trained them and gave them comfort. Alexion must leave Acheron's palace in Katoteros and go to Earth. He's given human form and arrives in Tupelo, Mississippi. He saves a Dark-Hunter's squire from Daimons, then asks the squire take him to his Dark-Hunter's home. Alexion has watched Dangereuse (Danger) St. Richard from Katoteros for the last year. There's something about her that makes him feel, and that's a feat in itself.

Danger meets with Kyros, who tries to turn her against Acheron. She then returns to her house to discover Alexion has made himself at home there. Almost believing what Kyros told her, the first thing she does is throw a dagger into Alexion's chest. He explodes into dust and then reappears in another part of the room. Danger learns that he's not just a Dark-Hunter but something more, a powerful "other" whom she should fear. But fear isn't really in Danger's vocabulary and Alexion touches her in a way no other man has ever done.

Danger opens Alexion's heart, a heart he thought long dead. He professes his love for her, even though he knows the moment he returns to Katoteros, Danger won't remember him or the love they share. However, while he's on Earth, Danger is the key to saving the Dark-Hunters.
