Blossom Culp and Alexander Armsworth were first introduced to readers in 1975 with the publication of The Ghost Belonged to Me. In that novel the focus was on family life, although the ghost story element added appeal and developed Blossom's and Alexander's psychic abilities.

In the subsequent novels in the series, Blossom takes the narrator's role.

Ghosts I Have Been (1977) and The Dreadful Future of Blossom Culp (1983) focus on her life in the community, although Alexander always figures prominently. Blossom Culp and the Sleep of Death is the last, to date, in the supernatural series, which has been very popular with young adults.
