Ok I found this in a storage locker a few years ago and held on to it.Marion Zimmer Bradley Hertage of Hastur vol.and vol2 It’s a science fantasy novel that was part of the Darkover series and was nominated for the Nebula Award for best novel in 1975.If you look on volume one you can see where her signature is above title.Not sure what it’s worth but I had it long enough so someone else can enjoy it Thanks
