Query: Too Good to Leave, Too Bad to Stay

This is a fabulous book and I highly recommend it to anyone who is struggling with relationship issues (and who isn't?). Unlike the typical self-help books, this book doesn't pretend to have some new formula invented by the author. She simply reports in a very insightful way: people who said they left for this reason were glad; people who said they left for that reason were not, etc. She doesn't tell you to add up the pros and cons, but rather gives you many specific directed questions to ask yourself to bring you to your own best decision. The author has a great writing style as well.
