Main characters: Tom, Alice, The Spook and Tom’s Mom.
This is one of the books in the series but not the first so you probably won’t understand.
Tom, his Mom, The Spook and Alice were trying to kill Ordeen in a castle. First they had to get there. They had to fight some witches and kill them all. When they got there Tom’s Mom was like “Run all of you or you will all die!" So they ran and then the castle blew up.
My favourite part was when the castle blew up.
I would recommend this book.
