I have fond memories from School of this book and although it was one of the books I was forced to read it still ranks as one of the best books I have read and so from memory I gave it 4 stars. I have just re-read it and have reconsidered my rating. It now gets 5 stars! An absolute page turning delight, still as exciting now as it was then. I guess the repeated and rather heavy handed signposting about evil spirits from evil deeds clinging to a certain something jars a little but it is a very, very small criticism of an otherwise hugely enjoyable book and definitely goes on my "books I will read to my children whether they like it or not" list that I am slowly compiling in my head just in case that happy event ever happens!
