My wife and I were given this book by a friend who had been struggling with depression, she said it was her "lifeline to sanity".
For us it has become part of our daily down time of tea and devotional reading. The prayers are nearly straight from the Bible but organized and expressed in such a way that they feed and elevate our souls. And the additonal writings about how to incorporate and enjoy praise in all of life is amazingly insightful and real.
At this moment I'm buying 10 more of these little gems to give as gifts to friends.
