Stephen King

Cujo tells the terrifying story of a once‑friendly Saint Bernard who becomes rabid and turns into a relentless killing machine. The novel focuses on Donna Trenton, her young son Tad, and their harrowing struggle for survival when they are trapped in their car by the ferocious dog during a sweltering summer. King explores themes of fear, helplessness, and the thin line between civilization and savagery, using the horror of a rabid dog as both a literal and symbolic threat. Tense, fast-paced, and psychologically intense, Cujo is a masterful study of suspense and human endurance under extreme danger.
