Baden: Formerly Demon of Distrust, Currently Demon of Destruction 
 Butterfly: on his chest 
 His curse: Well, he was dead for most books of the series. He was dead and without a demon even before the Lords started getting mating one by one. When he came back from the dead, he had no demon, i.e. we really do not know much about his suffering. We only learned that he really wanted to die before he died. Distrust also caused his hair to catch fire.

 I think this was the least anticipated book by the series' fans. Including me. 
 It was hard to feel for Baden in the beginning of the book. It seems as if Baden is a nice tortured guy, but I did not know him. He was dead but lived in our hearts for more than 10 books and suddenly he is back. It took me a while to understand him and his motives but l liked him and his story. 
 So Baden used to be a Lord and the keeper of Distrust. The only dead Lord. Haidee, currently Amun's mate, was used as Bait by Hunters in order to kill Baden. 
 Nowadays, he is back with an assignment by Hades. He needs to retrieve a coin from a dangerous man, Aleksader. When he visits him demanding the coin, Aleksader has just got married to Katarina. Baden instead of the coin, he takes Katarina with him. 
 "I'll leave with the coin...or I'll leave with something you value." 
 Katarina is dog trainer for drug detection dogs and for domestic protection dogs. She was blackmailed to get married to Aleksader. Aleksander Ciernik, is from Slovakia, where his family business includes selling heroin and women. And apparently Pandora (who escaped from the Realm at the same time Baden did) aids Alek. 
 Katarina and Baden's love story will be mainly naughty and funny. Katarina as a certified dog trainer will try to tame and train Baden and his demon. 
 I think i'm going to train a beast so evil his name is Destruction? 
 I've lost my mind. That's the only explanation. 
 And 
 If Baden were a dog, he would have barked at her, too. Maybe even nipped her. He would have been labeled aggressive, but as she knew, aggressive wasn't synonymous with cruel. 
 I cannot really say much about the story without revealing the secrets of the book. I can say that in the end, I really enjoyed it - although it is my least favourite in the series. 
 Anyway, I love the direction of the series and what happens to the entire Lord of the Underwold's family. 
 There is a cliffhanger in the end of the book about William and Gilly but I suppose we need to wait at least for two more years to see what will happen since Cameo's book will be next.
