Many of Norton's science fiction novels deal with strange planets, and are related to one another by other elements as well. Operation Time Search (1967) concerns breaking into an alternate world and bears a certain relationship to Star Gate. The Zero Stone (1968), to some degree, is related to the "Tie" stone in Star Gate. Their respective powers are different but the mystery behind these strange objects is an element Norton finds worthy of repeating.

A prolific writer, since 1963 many of her books have dealt with the occult and parallel universes.
