The strength of this book is that it favors breadth rather than depth.
If you are thinking about leaving the US but don't really know where you'd like to go, or if you have a destination in mind but don't really know what you don't know about emigration, this book is for you. Getting Out covers the top 50 destinations for US expats, with information about the quality of health care, cost and standard of living, and social permissiveness. Also included are brief accounts of the experiences of expats living around the world. There is also good general information about the different pathways available to the potential expat.
Reading it will definately leave you with more questions than answers, since any comprehensive emigration/immigration guide to all the countries in the world would fill a small library. Getting Out will give you the basics and point you in the right direction to find more in-depth information. You won't find anything here that will help you decide to settle in one country over another, but it will help you either narrow your list or give you reason to consider some place you otherwise would not have.
