Food of the Gods is one of HG Wells sci-fi novels, but it has elements of his later Utopian fantasies. A pair of scientists discover a nutrient that, if added to food, allows an organism to reach an enormous size. The substance is sloppily handled and begins to spread outside the laboratory, resulting in giant insects, plants and, by deliberate experimentation, giant children.

The plot is also sloppily constructed. There are some entertaining character sketches, but the story does not flow well and eventually the novel trails off into Wells' Nietzscheian vision of humanity's future. Of his sci-fi novels, Food of the Gods is the most disappointing.
