The second half of the title reads "What to do when you feel cheated or wronged" This book is a good reference book. It skims over a wide variety of problems you may face in everyday life. I find it a little too brief, but it does cover an amazing amount of topics. It includes sample letters in the back, for writing different people about different concerns.
If you get this book you will probably not want to repost it after reading. It's almost 4 LBS, so it's expensive to ship.
