 Obligation is the newest addition in the Underground Kings series. I've been so intrigued about Kai ever since he was introduced to us in the Until series. Kai is a serious alpha bad a** with a sweet sexy passionate side that is saved just for Myla. 
 This book was a hit and miss for me. Parts of it I absolutely loved, and other parts just didn't resonate with me. After the prologue, the story starts with Myla and Kai married and living in his house in Hawaii. They are in a marriage strictly for protection. He will do anything to keep her safe and protected, and this was his way. We are not given a lot of information about the situation. You are just kind of thrown into the scene and it's confusing. As you read on bits and pieces are revealed, but not everything is explained well, or in some cases at all. For me this type of beginning pulls my concentration out of the story and I have a hard time getting sucked into the book. 
 As the story progresses, feelings add to the mix and these two share a beautiful journey as they fall in love. I really love these two together. They have a connection that is felt the first time they are together and their feelings for each other pour off the pages. 
 So as much as I loved the romance part of this tale, I felt like the plot was missing information to keep the reader informed on the history and the business side of Kai. I felt the same for Myla and her past. She has been through some horrible situations and as much as I loved that Kai handled the problem for her, I felt like part of her story was skimmed over and just mentioned in passing. It left me with a lot of questions that were never answered. 
 So as you can see, I'm conflicted over this book. The love story was epic and it fulfilled every expectation I have for a romance book. I just felt there were things missing in the plot of the story to make it feel complete. Overall it was an enjoyable book and progresses the series along nicely. I just struggled with a few aspects. One thing I know without a doubt....Ms. Reynolds knows how to write characters that are easy to love and stay buried in your heart. I can't wait to see what she has in store for us next.
