I received this mystery for free and I voluntarily choose to review it. I've given it a 4.5* rating. This mystery had a lot in it. It had a little romance, a lot of action, some humor. and adventure. It was very hard to put down, just wanted to know what happened next. Because of the sex and the violence, it is not suitable for the under 18 readers. I really like Doris, the heroine in the story. Between her ex military training and her brain, she ends up getting the job done. I really enjoyed this series so far.
