The Darkest Fire is a short story, the prequel to Lords of the Underworld. The story is very interesting, sexy and hot.
It involves two characters that are damaged and wounded. Geryon is a guardian of hell's gate and he falls in love with the goddess, Kadence, who sentenced to observe the underworld. Despite of his feelings towards her, he feels insecure with himself because he's a beast - ugly and deadly dangerous. However, for Kadence - she doesn't mind at all. She loves him all and whole. And Geryon, he must saving Kadence from death for she is bound to the wall that separates the evil from reaching mortal realm, the Earth.
The chemistry between them is so wonderful which makes them a perfect couple! The ending is a bit unexpected but it is still a happy ending. I'm looking forward to read the next book!
