I enjoyed this story and its characters, as I did with the previous Magical Rom-Com w/a Body Count.
However, although it contains:
• some very funny stuff, major and minor,
• interesting history and creature creations (like who secretly lives below the reeking "abyss", and their mounts/allies — spoilers!) and non-standard shifter species' — though only one makes a major animal-form "onscreen" appearance (not counting the transformation spell, which isn't the same),
• a hero who, as the son of a werewolf and his werewolf-to-be mate-for-life, is the opposite of a man whore (He starts the book matter-of-fact about being a virgin!),
• and some exciting action scenes that involve both modern weapons and arcane abilities, ...
I once again just couldn't get fully into it.
The points that together made me knock off a couple stars:
1) The family dynamics and other interactions tend toward the over-the-top/cartoonish, e.g., the whole thing with Shane repeatedly kneecapping his friendly-enemy vampire(s), and being thanked for it.
2) Though I'll agree that Ernesto and his vamp clan, and the succubi & incubi who work for them, are miles better than the sex traffickers who got Shane (and company) on their tails by trying to kill him, I just can't be as blasé as everybody here is about sex-under-the-irresistible-influence-of-a-sex-demon. Not every person they feed from directly is a volunteer (even in the cases where they're treated well afterward, and despite the fact that "of course, they enjoy it"), and there's a radius of chaotic, libidinous influence the demons are gleeful about.
3) I also find it a bit jarring to have such a light tone throughout a book where the crime in question is so serious. I gather the heroine had to let herself be used sexually while undercover, and I'm not clear how often an incubus would have even been involved. It's certainly not something RJB dwells on, or explores in psychological depth, other than Marian's saying that the FBI makes sure agents get counseling. We don't actually meet any helpless, innocent victims of the sex-slavery ring, at all.
Oh, and the light touch persists through a sub-issue of anti-werewolf prejudice in the city where Shane was a cop, mainly relegated to low-status traffic duty. This led to his getting the least possible insurance payout and consideration after he lost his eye in an act of heroism. Still, he only shows bitterness a couple times, which makes him likable, but is somewhat implausible.
4) It's a bit long for such a "lightweight" book, and there is at least one slow patch where I was surprised by how much was still left on my progress bar — though I didn't *really* mind, since the characters kept me amused.
5) In a common ~flaw~ among action books and movies, Shane "takes a licking and keeps on kicking," recovering rapidly from serious injuries for a variety of only-possible-in-fantasy reasons. Even his lost eye (i.e., lost depth perception) doesn't hinder his shooting prowess or fast motorbike-riding.
6) Last but not least, in terms of disrupting my immersion, there's the poor proofreading. I marked nearly thirty errors. There were many missing small words, some random misspellings (incl. "burgular" and "in becase" — why didn't SpellCheck catch those, at least?), two misuses of who vs. whom (one in each direction), and twice "if you need rescued", (clearly the wrong verb-form; what's going on?). I also don't know what RJB has against using "that" to connect clauses, but there were several sentences which would have read more clearly had it been added.
Despite all those quibbles, I do plan to read later installments at some point. As for the sex-demon experience, I'll just do what I did as a kid reading past the mating flights in McCaffrey's Dragonriders of Pern: not think about it! (I somehow didn't even consider the M/M aspect there til years later; that wasn't the point (and still isn't — I read M/M sometimes now), given that I found/find the whole not-in-control, not-even-choosing-for-yourself premise so icky. 😕)
TL;DR: If you're less error-noticing than I am, don't take sex so seriously, and are just looking for a light, funny, sexy-but-fade-to-black urban fantasy read with some original elements, I can fully recommend these fun books. Otherwise, YMMV.
