Nate Jordan has harbored a secret crush on Logan for over three years, since their first meeting. Now they must work together to solve the case of a missing girl, but will be they able to resist each other?When I first saw that the latest book in Dane's Quinn Security series was going to feature Logan and Nate, I was ecstatic. I've loved Nate since he first made his appearance in book two of the series. And the glimpse you got of Logan in book three just made me want to reach through the pages and hug him, he seemed so despondent in places. Ms. Dane didn't let me down with this installment.The book picks up with Logan, now head of security investigations at Quinn after being wounded in the line of duty. On his first day at work, he discovered that Nate Jordan, the brother of his best friend's wife, is his new assistant. Nate has always had a crush on Logan since their first meeting, three years previously, and when assigned to work as his assistant, eagerly jumped at the chance. Together, the two of them have to solve the case of what happened to the missing socialite, Daria Sarna. Logan reminded me in a way of Gibbs from the TV show, NCIS, with his rules that he used to govern his life (although not quite as crust as Gibbs) and seeing Nate break down those rules one by one was entertaining. I loved the mystery element that was worked into this one, similar to that in book 2, and ultimately did not figure out who had done it, until it was revealed at the end.The cast of supporting characters, Riley, Declan, as well as Kasey and Canin, made the book an entertaining read. I could see the potential for at least a couple more books in the series, hopefully featuring Riley. My only complaint about the book is that the use of the term chute and channel when it came to the love making scenes between the two of them. There are just some words that don't sound sexy, and those are just two of them. I'm looking forward to more books in the series in the future (fingers crossed) and hope that they are as entertaining and well-written as this one and the previous ones in the series.
