This book can be read in about a half hour, tops. That's its strength--this book only contains the essential information and it's easy to access because you are not bogged down with what isn't necessary. It includes information about stone qualities, cleansing, empowering, love, and healing. Of course there are many stones not listed and many other uses, but this is a nice primer. If you didn't know what stones could do, you would have a good handle on it after reading this little guide.
