Wow. Just wow. I love Aeron but I suspected I would. I think these books do improve though I'm not sure if it is enough to actually recommend the series. Still Aeron being possessed by the demon of Wrath was a great story. Especially since his love interest is an honest to goodness Angel. 
 I did adore the relationship between Legion and Aeron. It was very reminiscent of Simi and Ash (The Dark Hinter Series) but as it turns out Legion is IN LOVE with Aeron as in thinks she's going to marry him one day. And she's a small reptilian like creature so that seems unlikely considering that Aeron looks like a man albeit a man with black wings. So, of course, when Aeron starts showing interest in the newly fallen angel Olivia, Legion is pissed and decides to make a deal with the devil (literally) for a human body to entice Aeron. This brings about another set of problems which are still being dealt with in the next book but all the while being entertaining. 
 Olivia is surprisingly refreshing. You would think an Angel might come off as a little boring but because there is so much she's yet to discover she's very bold and very fun. Granted she's not the most interesting but I do like her. I also loved that in this situation it was Aeron who was fighting the falling in love part while Olivia was already there. I mean it tends to happen but more often than not in this series the woman hasn't had too much confidence but Olivia seems to have it in abundance. 
 Overall a good story.
