Query: A waste of money

I've lived 52 years and this is the worst book I've ever read. It has spelling errors and misuse of the English language on every other page. The book is double spaced so it's actually half a book. All this could have been forgiven if it had an interesting story to tell - it didn't. I spent $25 on this book and am writing this review to keep others from wasting their money. I ended up throwing it out - something I've never done with a book. Didn't anyone edit this book????
