In The Mistake, the fifth volume of Joseph Delaney's series, the Spook forces Tom to train with another tutor to learn new techniques. But the latter makes a grave mistake: he sends Tom alone to face the greatest danger of his life. Will the master arrive in time to save his student? The Spook's Adventures achieved a remarkable feat: it amassed a huge fan base years before the books were adapted for film and other series became a worldwide craze. In fact, the first volume hit screens worldwide in 2013 with a stellar cast. In the stories, Delaney introduces Thomas Ward, the seventh son of a seventh son who became the Spook's apprentice. Since then, his missions have been arduous, as the master is a cold and distant man, and many students have failed. The plot is set again in the Shire, but this time in the northern part, near a large marshland. Tom's new master, Bill Arkwright, is a frightening, nervous man who forces him to make decisions that will have consequences for everyone. However, Bill has also proven himself to be tough and dangerous, a brawling Spook with inner demons, as well as some well-kept secrets in the mill where he lives. At the same time, a great secret of Alice's will be revealed, something that will forever change the relationship between her, Tom, and the Spook. Ogres, witches, and evil creatures are lurking. So, remember: avoid reading this book at night!
