3.5-4 stars 
 Kellan Kyle always wanted to feel needed, belonging, and a sense of family. His own family and childhood were not pleasant, and as an adult he searches for that belonging that he missed as a child. When Denny, as near to a brother as Kellan had as a child, moves to town and into Kellan's spare bedroom, Kellan meets Kiera, Denny's girlfriend. 
 Kellan and Kiera develop a fragile friendship, and eventually an intimate relationship. Both Kellan and Kiera struggle with the guilt and insecurity that come from going behind Denny's back and not knowing where they stand together. 
 This took me a long time to read. While it is longer than many other novels, it wasn't the length that made reading Thoughtful feel long. Knowing exactly where they story was going, and waiting for the pivotal scenes, I felt like I wasn't getting a whole lot of new material. Though it was from a different perspective, because it rehashes their beginning, a story that was very thoroughly told in Thoughtless, I couldn't get passed the feeling that I had read this before. The angst was still there, only instead of being torn between two men, it is the pain of watching someone while not being able to have them. 
 Particular scenes were priceless to read in Kellan's voice. But for the most part, I could have done without the repetition. I will say that the last 15-20% was my favorite part of the book, and I'm glad I continued to get to that point. 
 I was reminded that as much as I loved Kellan Kyle, as much as I loved the D-Bags, I wasn't in love with Kellan and Kiera's story, nor was I in love with Kiera. In fact, my dislike of Kiera was only reinforced by this alternate point of view. 
 The angst was just as tumultuous here as it was in the original story, but this time readers don't see the connection between Denny and Kiera, because Kellan doesn't want to see it. There were moments I almost didn't like Kellan. He is so focused on Kiera, on not having Kiera, that at times he feels whiny and emo, and that is not the Kellan that I remember. Desperate. Insecure. Feel like Denny became a non-issue in this. Kellan deals with his feelings about hurting Denny different than Kiera did. 
 In the end? I still want more of the D-Bags and their girls, but I can safely say I think Kellan and Kiera's story has fully been told. Fans of the series will love this story as a companion to the original trilogy and it does stand alone nicely. 
 I was gifted a copy in exchange for an honest review.
