This beautifully written book is a series of personal reflections and imaginative meditations that focus on the "First Week" (i.e., section) of St. Ignatius' Spiritual Exercises, during which retreatants traditionally focus on the workings of sin and grace in their lives. As such it serves as a good, practical introduction to many basic concepts of Ignatian spirituality such as consolation and desolation, detachment, and our deepest desire.
The strengths of the book are its lovely style, the honesty of the author's personal examples, and the creativity and depth of "Suggestions for Prayer and Discussion" that are posed at the end of each chapter. The latter clearly come from a wealth of retreat experience.
In the introduction, Silf modestly writes that her book "is not a way of actually making the Exercises." While that is technically true, many readers may feel they have begun to do so.
