From Library Journal:
A twist on the classic novel of a wife working to save her marriagethe other woman is a ghost. Willy and John leave Boston and his job for Nantucket and his shot at becoming an artist. The eight-year marriage is solid; there is family money for support and a lovely old house complete with an attic for John's painting. But John becomes increasingly obsessed by the ghost of the first owner, whom only he can seeand touch. What begins as a joke between husband and wife develops into a life-threatening presence in their lives. The book offers interesting insights into marriage, dependency, artistic temperaments, and the whole concept of ghosts, though the ending is not quite as satisfying as the rest. Not outstanding, but public libraries with other Thayer novels will want. Rebecca Sturm, Northern Kentucky Univ. Lib., Highland Heights
