I review all books on a scale from One to Five Pens including One and a half, two and a half, etc. Five being the greatest and one being the lowest.
Five Pens: A book to remember for a lifetime.
Four Pens: A greatly enjoyable book that I couldn't put down.
Three Pens: I enjoyed it partly but it wasn't anything to get excited about.
Two Pens: Don't waste your time reading the book.
One Pens: Don't waste your time reading the author. (Meaning I probably won't read anything by the auhor(s) again)
