Introduction
Headcase is the 4th installment in the "Necessary Evils" series and I absolutely adored this book just as much as the previous ones. I was really curious in how this author would implement the "twins" and yeah like typical James fashion, it kicked booty! There is something about her writing style that sucks me right into the story. I was so hooked into this one and eager to see where this one was going and how she was going to develop it and yeah I SO wasn't expecting some aspects, but it was pure fun anyway. She definitely tends to keep me on my toes with these and I dearly loved it.

Summary
Headcase is the setup where we have our two protagonists: Asa and Zane. Zane is a aspiring journalist, and barely financially surviving. He is recovering from the loss of his brother who was as close to him as a twin would be. He needs a story and a big one, and he begins to focus on a plan to get a story on the Mulvaney family and he runs to Asa at a awards dinner. They share a passionate night together, and when Zane follows Asa on a job, Zane is now at risk. And now Asa will need to convince Zane not to go public with what he knows. But as they begin to work on a story with a mystery surrouding college suicides, things get definitely more real for Asa and now the greatest threat to Zane is his twin who will protect him no matter what....

My Outlook
I really had a blast with this one here, and it was so interesting seeing how this would be developed here. I was intrigued to see where the author would take this one. The twins books I have really been looking forward to, because throughout the series you can tell that their connection is deep and they a psychological connection. I really adored getting to Asa's book though. He really likes things in the bedroom a bit more animalistic and that was interesting and I really loved the unique on take on BDSM that happened in this one here. But both are completely into it and I really enjoyed Zane as a character. I get nervous around journalist characters, but the author wrote this one fairly well here. The romance is passionate hot and deep. I loved the interchange between these two, definitely delectable in every way. I was hoping for a bit more interactions with Avi and Zane to be honest, just because of how close the twins are, but maybe we will see that in Avi's book. Definitely hoping for that.
