Beyond Black
by Hilary Mantel
True to its title, this is a dark book, but also very funny. But as well as containing well observed comment, great characters and a look at the often mundane nature of life, even for those on the "psychic circuit", there's a lot to unsettle. A ghost story should have a bit of a bite. It's also another beautifully written Mantel novel.
The two main characters are Alison, a psychic, with more than just body problems (she's very large) and her "assistant" Colette, sharp, cold and known as "the monster" at school. Alison Hart had a very murky and extremely painful and brutal childhood, something recollected in snatches throughout the book. A bad past that haunts her present in a literal way, and seems to be getting worse. People can be kind, nasty, maudlin and very cruel. Even when dead.
Very funny, but also very painful to read sometimes. A good book and highly recommended.
