This books starts off with a plane hijacking - yup, kinda far fetched, yet, it still worked for me. I loved the h, I mean she was super smart and witty and she knew herself very well. The H was strong but not in an overpowering way. The other characters in the book were pretty fantastic as well. 
 It was pretty much filled with non stop action. I mean the h found herself in so much trouble but the way the team came together to save her - holy cow !!! I found myself wanting to know more about the other characters because they just seemed really strong. There is basically no sex in this book, like there's a mention of it towards the end but truly that's it, so in that sense, it's a safe book. However, due to the violence - I'd watch for triggers. I liked it though, it was very well written.
