Bests & Worsts Reviews from Amazon

I thought the original book was great so I got the workbook. This is filled with grammatical errors and missing words. I found myself starting to correct it as I read. Had to stop. Is this a unedited draft? Or is this a fake book written by an imposter attempting to make money off the author? I thought Roger Press was the publisher. This may be serious copyright infringement. The typeface is fine for visually impaired - super large font. Difficult to read.
