This excellent scifi horror thriller is surprisingly complex, with a multitude of themes and a sprinkling of both conservative and progressive politics amongst some spectacular action sequences and classic underwater creature mayhem.
Obligatory nods to "Jaws" abound, including a mayor of a coastal town who cares only for their political career rather than the safety of the community and tourists. Also, the last third of the book is largely centered around the crew of a fishing vessel seeking to take down the killer shark. In this case, the creature is a 40 foot thresher shark, made gigantic and even more savage by the ingesting of experimental growth hormone products. Due to swelling of it's primitive brain, it is driven mad, attacking anything that moves in or floats on the water as a threat, thus providing a fairly satisfactory explanation of how a fish can pose such a threat to seafaring vessels.
The well-paced action is also balanced by an interesting cast of characters. I've read too many of these modern horrors where every character, even those with whom we are supposed to sympathize, is a whiny, snarky, sarcastic ass. The dialogue of such stories is nothing but a series of put-downs and cusses, sounding like a locker room full of 8th grade boys. Though there is some of that here, there are plenty of refreshingly human personalities depicting people who respect one another and who stand for something. The bad guys are kind of stereotyped, and the main male protagonist is a drunken grump, but as a whole I was invested in the cast and their fates.
The book also delivers more than just grotesque carnage from a mouth full of teeth, from it's highly sensitive ecological messaging, to it's exploration of grief and alcoholism, to it's support of law enforcement and it's depiction of cowardly and ineffectual politicians scapegoating their police force to hide their own incompetence, to it's general distrust of the news media.
But most importantly, this novel will make you afraid to get back in the water... Again. The perfect book to read during Shark Week, during your summer vacation, or anytime.
