Grogon's short book is an excellent entry into Pope Francis' encyclical Laudato Si. This book contains short but meaningful reflections, a month's worth, on the encyclical about the care of Creation which includes all creatures: nonliving, living, and human. Grogan references the encyclical throughout. The encyclical is complete with good ecololgical and environmental studies, scripture, and church teaching but is a bit dense. Grogan's book is a great companion focusing on spirituality and our relationship with God. Grogan's book makes a great private devotional or might be used as a group study with the encyclical.
The book has an Introduction, two parts, a Postscript, and a Further Reading section. Part One: The Doors of Perception has 13 entires and a summary. Par Two: Repair My House has two entries.
Highly recommended for those concerned about Creation (nature and the environment), those looking for an entry into Laudato Si, and those looking for a Christian perspective on nature.
