"Living in the Companionship of God" by Jan Johnson

This book is geared towards a retreat audience, but anyone can use it. After all, as the book points out, anyone (alone or in a group) can take time aside to focus on God anywhere and for however long they wish. The book first defines the notion of retreat and then starts going into how to analyze Scripture and grow closer to God. Verses and sections of chapters are wholly repeated three or four times. Questions and prompts are given with space in the book for readers to respond. From having confidence in God to pouring out your heart to Him, this book is helpful. Some famous quotations and prayers from (thank goodness not "to") saints are included. This short book can be completed in a day and so should not be the sole resource one uses on a retreat.
