The Last Apprentice: The Spooks Tales and Other Horrors Joseph Delaney, Patrick Arrasmith, random House, New York, 2009.
Much of the material in this book is review. However, it does tell the Spooks story and he became an apprentice and his first dealing with witches. He was traveling to school and become lost and a spook rescued him. He was a seventh son of a seventh son and his thumb bones would have been a prize to a witch, who almost had him. The spook was able to help him, and he was able to help the spook bind a boggart and a witch.
The parts that were mostly review was the story of the creatures of the dark and Alice’s story. New material was the story of Grimalkin who told how she became the witch assassin—with the goal of destroying the fiend.
