Hyperion Publishing was founded in 1991. So far, it has created four Lost book: Endangered Species, Secret Identity, Signs of Life, and Bad Twin.

Hyperion Publishing was involved in the Lost Experience. The Hanso Foundation complained to them in a letter stating that the information about the Hanso Foundation in the book Bad Twin by Gary Troup, is not accurate, and they threatened them with legal action. Later, a newspaper ad by Hyperion Publishing said that information in it is true, and they backed up the book and the author.
