I'm not really sure how one categorizes this book; it is a combat suspense with elements of romance. Driven by the inherent danger in mixed gender combat situations, it doesn't shy away from the brutal reality. This is not a fluffy, sweet romance where men are heroic and women are cherished. This is ugly, violent and confusing...and I loved it. It takes a difficult intersection of two lives that are polemic in their loyalties and goals and plays the hard cards. My one gripe about the book is that it ends before the final external conflict is resolved though our protagonists have. It does have a happy ending for those who can take the brutal beating upfront.
