Aiken never disappoints! I've seen a lot of other readers complain that this book is more enjoyable for children and adolescents, but it's such a well written mystery/suspense/horror story! True, themes such as school bullies, tree forts, and somewhat childish caricatures of historical figures might not be very appealing at first glance for adults. However, the atmosphere that Aiken builds up is amazing, and there are definitely parts that will creep you to no end.
