Based on a real English witchcraft case from 1593, Weird Sister is a chilling, delicious book. Far from being a tedious historical 'recreation', it reproduces the atmosphere of the original case (detailed in a contemporary pamphlet) brilliantly. The book focuses on the spooky incision of the magical into the ordinary world of the modern Throckmorton family whose ancestors indeed accused and caused the deaths of three 'witches'. The characters are well-drawn, and the tale, though sometimes sexually explicit or shockingly violent, is a perfect, dark gem. There are one or two divergences from the 'real history' of the case in the modern version, and the reader is left questioning what was really what (and who was who) in a pleasant, shivery way.
