Darkness Unmasked is the 5th book in Keri Arthur's Dark Angels series. What started out as a pretty good series really surpasses my expectations with this installment. Whereas Darkness Hunts focused more on the secondary story rather than the main story arc, Darkness Unmasked brings the attention back to Risa's quest of finding the keys and her mother's killer. Of course there is also still a side story. Risa is tasked by Director Hunter to find her lover's killer, in the process we find out just how scary Hunter has truly become. 
 It's not so much the key storyline that drives the story, it's Risa's relationships. There is so much that happens in this book, it almost all blends togethers. But there are key moments that stick out and keep me thinking aobut them even after finishing the book. 
 I like that Risa and Azriel finally decided to be a little less distant with their relationship. They do make a lot of headway, but they are still weary about what their relationship means to each other as well as in the grand scheme of things. I like the two of them together a lot. Keri Arthur did well creating / writing their relationship. Of course in true Keri Arthur fashion couples usually get put through the wringer before they get their HEA. This series is no different, but I keep hope alive and can't wait to see where the next books take our hero / heroine.
