This novel is a readable but deeply flawed potboiler detailing the destruction of America's food supply by a coordinated biological and chemical attack. The premise is interesting, if decidedly far-fetched, but the execution is frankly weak, with too many trashy interludes that distract from the main plot and not enough introspection.
The novel is best when it looks at how American society and particularly the American government would react to such a disaster. In the wake of COVID, the depictions of politicians floundering to deal with the crisis or even to profit off of it are a little too convincing. However, at times Masterton is a little too sanctimonious in his attitude toward what I would consider necessary measures in the face of such a calamity, such as federal officials ensuring they have enough food to keep running the government and the need to keep the disaster quiet in the initial phases in order to prevent a descent into chaos before the government can prepare.
The novel also maintains a good pace with lots of action and thrillingly gruesome violence, especially in the second half. Particularly memorable is a scene where a religious fanatic tries to replicate the miracle of the loaves and the fishes with catastrophic results. However, all too often, the novel stalls in order to give us explicit, at times bordering on pornographic, sex scenes, perhaps most notably a rape scene where two sisters are forced to perform sex acts on each other. Also, there is a decidedly misogynistic subtext where the protagonist cheats on his wife with little to no consequences, while the wife suffers for cheating on him.
Furthermore, the plotting gets weak towards the end. The question of who carried out the attack is pushed too far into the background, only to be clumsily resolved at the end of the book. Major supporting characters, such as the protagonist's mother, just disappearing with a handwave. In the end, it's readable, but not particularly good.
