The Last Apprentice #6: Clash of the Demons by Joseph Delaney

This book is the sixth in the series, and I gave it a rating of five out of five. Tom and the other main characters travel to Greece to help Tom's mother combat the arrival of the Ordeen, a dark creature that will release hundreds of blood-sucking witches to destroy all living things. Ironically, they must team up with the same witches they were fighting in the previous book to defeat this new danger. Tom is torn between using the powers of the dark to stop the Ordeen and the Fiend and his duty to stop the Dark forces. Tom, his mam, the Spook and the rest of the gang travel across the ocean together on a ship with the blood-thirsty witches. They are attacked by pirates at sea, and then they're attacked by other witches and dark creatures once they land in Greece. Tom wonders about the truth of a witch's vision that Alice will die, and the same witch tells him that his life will be sacrificed to the Ordeen. Tom discovers a terribly horrible truth about his mother, and the Fiend wants his soul. What's a boy to do?

This plot has a great deal of action, and the problems keep stacking up against Tom. He defends himself a little better than in previous books, but the dangers become even greater. He realizes that the lives of everyone in the world depend on his ability to defeat the Ordeen and the Fiend. The format of this book is the same as the others, so you'll like it if you've enjoyed them.
