This is a book that covers methods and ideas behind the practice of walking through your community for the purposes of prayer.
The authors begin by making a biblical case for the power of prayerwalking. I found some of the examples from Scripture to be a bit of a stretch and probably unnecessary to give. I'm not sure why we always feel the need to justify something good by finding examples of it in the Bible or stretching things to fit what we are looking for. There were also, however, lots of helpful examples within this section as well.
After this, the book moves on to practical ways in which to engage in prayerwalking including helpful tips and lots of sharing from others personal experiences to help people get started.
If you're looking for some more variety in your own personal prayers or the prayer ministry of you church or organization, this could be a helpful read for you.
