The Last Apprentice: Night of the Soul Stealer by Joseph Delaney
After Revenge of the Witch, I wondered how quickly the premise would get old and these books start to all read the same. Three books in, this hasn't happened yet, and I'm starting to think it won't.
The weather is cooling and it's time for Tom and the Spook to move to his winter house. It promises to be a long, cold winter and Anglezarke is nowhere near as nice as Chippenden. There's no garden-- the witches and boggarts are buried in the basement. The Spook's past is coming back to haunt Tom with dire consequences. It's going to be a bitter winter, and when the Spook is taken out of comission, it's up to Tom to make sure that spring will eventually come.
The dark is gathering forces and it's starting to become obvious that these first few volumes in the series are just the warm-up for what's about to come. I can't wait.
