I've loved romance novels since...like forever. I read across most subgenres of romance. I also write fantasy/paranormal and new adult romance.
I really like Annika Martin/Carolyn Crane's books, but this one was just okay for me. The set-up was strong, reunited childhood friends on opposite sides of a Russian mafia war, but it just lost steam.
The pacing was fine and I even thought the actions scenes were strong, but the romance--ahem, and the alluded to dirty sex--was few and far between and not particularly dirty.
So, if you are the type of reader who is annoyed when characters in a romantic suspense story stop during a chase scene to have sex, this is the book for you. I, however, never mind when that happens. ;)
A final note: I liked Mira and Aleksio as a couple. Their character arcs were subtle and made sense, I was just expecting more of a dark romance.
