Decent writing, interesting premise, but a few flaws.
On Amazon (where I originally posted this review, right after finishing the e-book), I gave it 4 stars, for 3.5 to 3.75 rounded up.
A number of my favorite authors write urban fantasy and/or paranormal romance (Patricia Briggs, Ilona Andrews, Eileen Wilks, Nalini Singh, et al). This falls about in the middle, though if you're specifically looking for detailed sexy times, look elsewhere: this one is basically fade-to-black. That's not usually a negative for me, though honestly, given the lead characters' general attitude and dialogue, I was a little surprised.
The relationship seems to develop a bit hastily, from her merely being annoyed by the distraction of her sexual attraction to him, to trusting him (a reporter!) with a full reveal of the secret she'd been raised to protect above all else, at all costs. Yes, he'd begun to suspect, but it's such a crazy idea that surely she had other options -- if only to protect him from the "elimination" she just barely convinces the Pride leader not to carry out.
As for her semi-former Pride, it's shown as having a very rigid and extreme set of restrictions, driven by secrecy, and enforced by violence. She has some warm childhood memories, but they're outweighed by the cruelty of how she was cast out at only fifteen.
N.B., at first I wasn't clear on what kind or kinds of cats they Change into, especially given the kittens in the nursery cribs, but it was eventually stated that adult Felis become the feline version of the classic horror-movie wolfman (something like Curran's "Warrior form" in the Kate Daniels stories).
When she realizes who killed the Felis wife/mother/schoolteacher whose death she and Bran are investigating (fairly realistically if a bit superficially depicted, BTW, with speaking to family and contacts, internet searches, visiting the crime scene, and -- since she's Felis -- sniffing), it becomes clear that all the Felis will have to re-evaluate some of their longtime assumptions and ways, which hopefully will be interesting to see play out in future volumes of the series.
The writing is mainly fairly smooth and well-edited, though it didn't have any passages so perfectly crafted that I had to stop and reread them just to appreciate the author's imagery or emotion, but that'd just be what tips a 4.5 to a 5.
However, there was one shortcoming that an editor should've caught: redundant body language. Too many times, a character (not always the same one, so you'd say that it's a trait of that particular individual) would touch, tap, or rub the tip or side of their nose. It became noticeable, and I wasn't always even certain what emotion it was meant to convey: at times uncertainty, or confidentiality, or...
Also, if she's living on ramen noodles and canned tuna (finding evidence on cheating spouses, locating the occasional runaway teen, etc., doesn't pay that well), shouldn't she be more upset about having to throw out clothes and bedding damaged by blood and/or odors too unpleasant for her sensitive nose, not to mention the issue of whether she'll get paid for the destruction of more of her property?
I have to confess, though, that the element that bugged me the most was something most readers would probably consider a trivial one. In a number of scenes, mention is made of claws painfully cutting their way out at/between the knuckles -- and leaving visible marks to show when that partial transformation has occurred. Given how quickly the full transformation can take place, and how little pain the shifting of bones and muscles seems to cause (again, see the scene with the Felis kittens) that seems inconsistent. Worse, as much as I can enjoy Hugh Jackman's Wolverine, his type of "claws" make no anatomical sense. A cat's retractable claws are nails, made of keratin just like ours (not of bone), and *hinged* (not shrinking/growing) in their own openings; no skin needs to be cut and re-cut. I guess on a human hand, they *would* have to grow, but it'd just be a thickening of the nails, hardening and extending beyond the fingertips -- and partly closing said hand would be the last thing you should do to *use* them: they wouldn't stick up/out like brass knuckles, for heaven's sake! (Declawing involves removing the first joint of each toe, BTW -- so don't make your pets endure this lifelong handicap just for the sake of some furniture!)
Okay, rant over. In short, it's a pretty good story, with pretty well developed and appealing lead characters. I do plan to continue with the series, but I doubt it'll ever be among the names I recommend to everyone.
