Ten years ago in 1993 the author, Janet Fraser-Smith, published the first issue of this book for Christians on cross-cultural marriage preparation, Love Across Latitudes.
Though not described at the AWM website, this book is "designed to help you (as a Christian) to describe yourself, and to broaden your understanding about how individuals from differing backgrounds approach life." It will assist you in answering the question, "Is this the right person for me?"
Janet Fraser-Smith when authoring this book was the wife of a regional director of AWM, and together they had served in churches in Egypt, Jordan, France and the United Kingdom. She has observed and counseled in many cross-cultural relationships.
