Query: The Amulet of Samarkand is a must read book!

The Amulet of Samarkand is a thrilling and suspenseful book written by Jonathan Stroud.I very much reccomend this book. Nathaniel is twelve year olds and is a magician's apprentice. His master is Arthur Underwood who is a magician but not a very good one. Nathaniel summons a djinni, demon, called Bartimaeus to steal the Amulet of Samarkand from a magician, Simon Lovelace, who had humiliated Nathaniel earlier. Unfortunately Simon realizes Nathaniel has the Amulet and kills Nathaniel's master and his wife. Filled with anger and revenge Nathaniel accompanied by Bartimaeus set out to Heddleham Hall, where Lovelace is making plans to take over the country. Nathaniel succeeds in stopping Simon Lovelace's plan and is rewarded with a new master. The book has a unique plot and is a must read. I advise reading this book in the morning because it is a hard book to put down.
