Marion Zimmer Bradley's Light series consists of:
Ghostlight, copyright 1995, a hardback in mint condition, the story of psychic Truth Blackburn, with dust cover, original price $22.95
Witchlight, copyright 1996, a hardback in mint condition, the story of Winter Musgrave (one of Truth's clients), with dust cover, original price $23.95
Gravelight, copyright 1997, a hardback in mint condition except I wrote my name and date I purchased it on one of the inside pages, the story of Wycherly Musgrave (another of Truth's clients), original price $24.95
Heartlight, copyright 1998, a trade paperback, a story which I think runs parallel to Ghostlight, original price $15.95.
It's been so long that I read these that I remember very little of them!
The top three hardbacks are first printings.
