In short-short, I liked Patricia Briggs's Moon Called. It wasn't my favorite book ever, but it was solid and satisfying, with enough character voice and surprises to keep me happy with the end result, especially for a clear series starter.
I had one nit-pick with it as far as yanking me out of the story, and that was the use and lack of use of contractions in various places. I know, that sounds stupid, but when a reader expects a character to say "I'm" rather than "I am" it gets kind of stumbly.
For a plus point, I particularly liked main character Mercy's pace with revealing information and in explaining her own logistical conclusions.
All-in-all, I give this book a strong Borrow, a Buy if you're really, really into contemporary supernaturals.
On a shallow note, a peeve and praise for the cover designers.
First, the peeve. What mechanic worth her grease would wear her work shirt a). unbuttoned and tied up that way, and b). with a push-up bra? I cannot suspend belief enough to think this covergirl mechanic seriously thinks she'll draw in business this way, even from skeevy rich dudes. Skeevy rich dudes go to strip clubs to see girls in knotted, push-up bra-ed outfits, not garages. Mercy's not stupid; she'd dressed professionally, but for functionality, and so her customers see her as a competent business woman.
However! Kudos to the person who sized and placed the endorsement blurb by Charlaine Harris. It's noticeable without detracting from the cover image, title, or author. That's tasteful and I applaud your class with that issue, Unknown Cover Person.
