Rating System

Excellent
Books which I enjoyed so much I would keep and read again and again.

Very Good
Books I may keep and read again, but which had a few flaws which prevent it from getting the top grade.

Good
Books I still enjoyed reading but wouldn't necessarily ever read again. They may have been rather bland or other factors, such as weak plot or characterisation, bought the mark down.

Poor
Books where I only enjoyed bits of it or found it dull. It could have been an effort to keep reading.

Terrible
Did not like the book and may have found it very difficult to finish reading.
