With Roach at our aspect, we trip the realm, assembly murderers and mad scientists, Eskimos and exorcists (who have sometimes administered holy water rectally), rabbis and terrorists―who, it seems, for functional purposes don't disguise bombs of their digestive tracts.

Like all of Roach’s books, Gulp is as a lot approximately people because it is set human bodies.
