Sometimes I find it hard to decide what I'm looking for most in a book - a strong plot, engaging characters or a theme that simply strikes a chord - this story has all three by the spadeful. Switching between the present day and the 1920s, more than blood alone binds twins, Isis and Osiris, to their dilapidated mansion. An inventive and atmospheric novel whose grim humour is a hair's breadth away from the grotesque.
