Transracial Adoption: Foundational Principles for Healthy Cross-Race Parenting by Be the Bridge
This short book offers both information for prospective adoptive parents to seriously consider and also action steps for adoptive parents as they seek to parent their children well. While I don’t agree with all of the stances around racial issues, it still contains many ideas to consider.

Honestly Adoption by Mike and Kristin Berry
In this book, the authors (who are the adoptive parents of eight children) talk openly about some of the challenges of engaging in adoption and foster care. They offer helpful advice in meeting each child where he or she is, and they also touch on parenting older children and working through having birth order shift in the family. It is an encouraging read and one I plan to return to as my children grow.
