Here is a picture of some of the 'light' reading we've been doing to get ourselves ready for the adoption! Some of it (the large blue book - Adoption Parenting) was required and we had to take an exam on it... others were recommended. I really enjoyed "Adopted for Life." I still have to finish "Beyond Consequences, Logic and Control," but I hear it is excellent.
If you are just beginning your adoption journey, the "Successful Adoption - A Guide for Christian Families" is helpful. It gives you some good examples of letters to the birth family or to the Country Officials for your Dossier.
