Hammers — Ron Dakron

A young geneticist perfects a medical serum made from both human and shark DNA. In her hurry and ambition, she skips biotech protocol and tries the serum on herself. But a mistake has been made - instead of shooting u a fraction of shark DNA, she's popped the entire hammerhead genetic code. Oops. Hammers is a comic novel about people turning into sharks. Set in a modern biotech city, it follows five characters as they mutate and fight for dominance, sex, and a reliable source of fresh squid. Hammers is a classic transformation tale in the genre of Frankenstein.
