I've been reading MS Parker's books for a while now, and always enjoy them. I liked the first two books in this series as well, so I was eager to read, "Take Me Sir".
It was fun to see characters from the first two books, and the connections they have to Dean and Kyndall. I really liked Kyndall and Dean and their story. She's strong and incredibly intelligent, and can take care of herself. I like that Dean doesn't try to take over her entire life. She expects him to trust her and for the most part, he does (aside from a misunderstanding that, while understandable, is pretty huge). I prefer "Alpha" men like him: he can appreciate and respect a strong woman. He doesn't want someone who can't stand on her own two feet, but he's also willing to jump in and help her when she really needs it. He's smart enough to appreciate her intelligence, and their age difference doesn't phase him at all. They're a really well-balanced match.
The only disappointment I had with "Take Me Sir" was that it wasn't longer. I thought that things were wrapped up a little fast - I would have loved a little more suspense, tension. That doesn't mean I didn't like the ending though. I just wanted a little bit more action and detail before we got there. Some of MS Parker's other books do this really well, so "Take Me Sir" seemed short in comparison.
I also would have just loved to keep Dean & Kyndall's story going a bit longer, because I really like them together.
