I got an email asking how I base my reviews, so I came up with this as my stated review criteria.
5 stars: Book brought new detail or information to light, nothing else like it out there or a great update. Well written, few typos, well edited.
4 stars: Good information but nothing "new", written pretty well; good but not outstanding, has some issues.
3 stars: In some form or fashion the book has flaws whether it be editing or content, usually just average content.
2 stars: Shouldn't be used to start fires, but possibly pretty close.
1 stars: Probably shouldn't have been published and I want my money back, brings nothing of value whatsoever.
**Ideally, all those stars are qualified/explained with the write-up
If you disagree or have some things to add, PLEASE leave a comment :-)
