An Award-winning novel by Neil Gaiman, American Gods is a blend of fantasy and mythology, both modern and ancient. Published in 2001 in the United Kingdom by Headline, this novel alludes to themes that were previously explored in Gaiman's The Sandman narrative.
The novel centers on the idea that existence of gods and mythological creatures is dependent on humanity's belief in them. Therefore, the gods are only as strong as the belief that they are showered with, and as this belief wanes, so does their power. Indeed, the gods are shown as a direct projection of the faith that has produced them.
