I really liked Idess and Lore's story. The only problem I had was how fast they got together. From the time they met until the time they bonded was like 4-5 days. It seemed longer with all the action in the book but that is the actual time line. I think maybe some more build would have been interesting. The Assassin's Guild wasn't to spectacular a spot either. It felt pretty one dimensional. Althought the tiger shifter Sumil was pretty cool. 
 I really liked Lore and Sin and the storyline with the other Sem bros was really great. (view spoiler)[I'm glad they finally did away with Roag. It was getting super tiresome always having him be the bad guy. Azagoth was way rad! I'm really interested in him as a character and I hope he will be in future books. (hide spoiler)] 
 I was happy to finally meet Sin. (view spoiler)[Lore's twin sister and only female Seminus demon in existence, EVER! (hide spoiler)] She seems like a really interesting character and I'm interested in how her story will play out next.
