Gideon: Demon of Lies 
 Butterfly: on his right thigh 
 His curse: Well, lying actually. He cannot say a single truth without suffering. 
 Scarlet: Demon of Nightmares 
 Supernatural ability: Scarlet is half goddess as the daughter of goddess Rhea and a Myrmidon warrior. She is also the keeper of Nightmares and for that reason she has a butterfly tattoo on her upper thighs. Apparently the Lords are not the only keepers of the demons that escaped PandoraaEUR(tm)s Box. Thus, she is using the nightmares to defeat her enemies, especially during the night time when she is extra strong. 
 I absolutely hated this book. I think it is the worst book from the Lords of the Underworld series and one of the worst ever written. Extremely badly written. Awful. I donaEUR(tm)t know how I managed to finish it. I had to try really hard. 
 Hahaha I am sorry I could not resist talking like GideonaEUR| 
 You see, whatever Gideon says he means exactly the opposite. This may drive you crazy when you read this absolutely brilliant book trying to understand what Gideon is talking about. But it will also cause a lot of laughing out loud moments. 
 The anger seemed to drain from him, something hotter, sultrier taking its place. Those rasping pants never slowed, and in between them, he said, "You're so unbelievably...ugly." The last was offered hesitantly, as if he feared she wouldn't understand what he was trying to tell her. "You don't make me ache. You don't make me hunger for so many things. Dirty things. Wicked things."
