Back to Blackbrick is a great book with lots of twists and turns. There are two things I didn’t like about it. The first is how it keeps jumping from what is happening now when Granddad’s brain is messed up to what used to happen in the past when his brain isn’t messed up. And the second is that the sentences where people talking are often in third person, so there are less quotation marks than I would expect.
A couple of the things I really liked about this book were that at the end of the book it makes it sound like real life, and second, the author developed the characters very well.
This book has what every great book needs: action, adventure, surprises, and a touch of magic. I would give this book 4/5 stars and would recommend this book to ages 10-14. Have a great time reading this book.
