In the Garden of Iden is a 1997 science fiction novel by American writer Kage Baker. Although it is set entirely in the 16th century, in Spain and England, it is a science fiction story revolving around the activities of a group of immortal cyborgs, individuals who appear human but have been transformed by high technology. American illustrator Michael Koelsch painted the cover art of Baker's first three novels in The Company series, beginning with In the Garden of Iden.
