Witch's Business

I just finished a book called Witch's Business by Diana Wynne Jones. This book wasn't one of my favorite book's but it was very exiting and mysterious. I started reading the book because my sister read this book in 5th grade and she said it was pretty good so that's why I read this book. I also picked it because Halloween is coming up and this book has witch's in it. The book's main characters are Jess and Frank they have the regular brother sister relationships where they get in fights some times,play pranks on each other,and scare each other. This book had some parts that were unpredictable and it had some pars that were very predictable. I like this author because she put's a lot of detail into her book's. Overall I think this book is interesting but I prefer a book that keep's me on the edge of my seat.
