Having enjoyed the two "prequel shorts" set in the UF world of Hell's Belle and featuring Nina Martinez out in the field with her Blood Ops partner, the smart-ass vampire Frankie, I was looking forward to reading this full-length novel.
Unfortunately, the shorts basically whet my appetite for something that does not exist: namely, a novel featuring more of Nina and Frankie working cases as part of the Blood Ops team. Why? Well, I guess I should have paid more attention to the fine print of the book's official description instead of relying on my enjoyment of the prequel stories, because Hell's Belle entirely bypasses Nina's dozen or so years as an agent. Strangely, one of the two stories reappears here (word for word?) as the Prologue, but that prologue is disconnected from the rest of the book. What follows (i.e., Chapter 1) starts with Nina beginning anew as a barmaid after returning to her hometown, and there's really not much seen of her Blood Ops team because Nina's busy, well, dating and sexing FBI agent Max, and dealing with her own hybrid witch/vampire nature. There's ostensibly a plot involving a supernatural murder mystery and some magical knives, and Nina's family history, but there's not much to it except for maybe the family stuff.
It's almost as if the shorts/prologue bear only passing relation to the novel apart from the broad strokes of the characters' most basic functions and personality traits. Also, the 30-something Nina here sort of varies between seeming her age and seeming far younger. She supposedly spent her whole adolescence in Blood Ops training and then a dozen years in the field, but seems either remarkably out-of-practice or just plain ignorant of the supernatural a lot of the time, which results in many info dumps throughout the narrative. There's vivid description of the setting (Providence, RI, which author Greco clearly also calls home :), but not the kind that creates atmosphere. The sex scenes are kind of awkwardly written. The relationships between the FBI, the Dept of Defense, and the Blood Ops unit are never explained at all.
I would give this 2.5 stars.
I actually like these characters and their snark, and I like the idea of the Blood Ops unit. This is all a solid basis for great UF (though the focus on Nina's dating FBI agent Max pulls things more toward PNR than UF...). But ultimately, this novel was just okay for me, and my experience of it also suffered from (understandably!) misleading expectations.
Keep the short stories coming, though!
