I read this as a pre-read for my son, but I did enjoy it myself. It certainly is spooky and I liked the characters of his aunt and live-in housekeeper. I did find it difficult to believe that the main character could just "pick up" jousting, fencing, swordfighting, and such without any training. But overall, it was a fun read. Not her best, but better than a lot of the schlock published for YA readers these days. If you liked this, you'll no doubt love the Green Knowe series by L.M. Boston, which are also about a boy staying in an old house and coming across previous residents, but are better written (IMO).
