The Guardian of Willow House

Possibly a genre novel, based on the publisher's description. Verifier should check, and update the author's bibliographic comments as appropriate.

Data from OCLC which gives the ISBN as "0-671-68008-0", a number that falls far out of the range of ISBNs assigned by Pocket in that time period. The same ISBN was used in 1989 for a Star Trek novel. The ISBN from OCLC does appear as an SBN on the book's copyright page, seen on eBay, minus the first 0 (as does the month and the cover artist), and the spine has the full ID on it; the LCCN on Open Library, 77003720, isn't on the LOC site.
