I obtained this book through the Kindle Unlimited program.
I do NOT read horror. It's on my list of exclusions. However, the person who asked me to read & review this book wasn't aware of that, and asked so cordially, that I decided to give it a shot.
It wasn't bad at all. Yes, there is a monster, and yes, it eats people, but I wasn't creeped out in the same way I would be if somebody attempted to tell me a ghost story. I say 'attempted,' because they would NOT be successful, whether I had to leave the room or throat-punch them.
The setting is quite authentic, in a fictional city just outside metro Atlanta. I've lived in places much like this, both on the north side and on the south side of the city, and Quinn does an excellent job of describing the countryside, as well as the economic plight faced by smaller communities absorbed into the metroplex. In fact, the villain of the piece has a quite sympathetic introduction; he's a BBQ restaurant owner who has lost significant business to the chain restaurants that have moved in. He, on the other hand, hires locals, and buys supplies from local merchants. He probably serves better BBQ, too.
The author has also done his historical research, too; the 12th Michigan Volunteer Infantry, who are eaten by the monster, was an actual unit that fought down from Tennessee, Kennesaw Mountain, fought in the Battle of Atlanta, then headed west chasing General Hood into Alabama, from whence they were mustered out unless eaten by monsters). The enlisted soldiers suffered 102 fatalities from enemy fire, and 94 deaths from disease; no count of monster-related deaths is recorded.
Other noteworthy accuracies that I had to look up: the throttle on an ATV is NOT like the twist-grip throttle on a motorcycle. I'm now trying to recall if I have ever actually been on an ATV, and can't recall; but, the throttle works like he says it does. Secondly, the Bad Guy recalls worthless draftees (with some exceptions) in his MARINE company in Viet Nam; I could not remember any Viet Nam era draftees to the Marine Corps, only the Army, BUT I checked it out, and there were 42,000 drafted Marines during that time, and likely most of them went to Viet Nam.
I could have used more character development of the teens in the book, especially since it IS primarily their story. We get some insight into the primary male character, and a bit less into the primary female character, but the others, not so much. Exception: the two girl friends of the the main female character.
Of particular value to me is the respect given my redneck kin. Usually, country Southerners are depicted as stupid and slow. and that happens not to be the case. Yes, SOME of us DO have accents, as noted in the book, but most of us do not. Even the teens are given credit for having brains; the main character has been accepted at UNC-CH, which is quite rare for an out of state student, while two others have been admitted to Georgia Tech, one of the foremost engineering schools in the country. Furthermore, the protagonist is seeking a business degree, and recognizes that Georgia State is an excellent choice. (Admittedly, I'm not impartial, having earned three degrees there myself.)
Dim opinion, based on 45 year old knowledge: the Claymore mine IS a remarkably effective ambush and defensive weapon, but I don't believe it would do as much damage as described in the story. However, I've only fired one of them, and that was in 1972, and I'm not an expert. That IS my only weapons quibble, and I'm pretty much death on firearms mistakes. (NOTE: a character refers to them as 'land mines' which they AREN'T, but that's the character's ignorance, not the author's.)
While I will NOT venture further into Spook Land, this wasn't bad. I would like to point out, however, that were such a monster existing in a pond near Atlanta, it would NOT be worshipped and fed human sacrifices. Instead, businessmen would be lining up to build a theme park around it, and raking in the tourist dollars like crazy.
