I was really blessed by [i]The Power of Prayer, The New York Revival of 1858[/i] by Samuel Prime. It's a wonderful account of the revival and also chock full of wonderful testimonies of answers to prayer. Very encouraging to keep praying even for the hardest cases!
Lately I have enjoyed Getting Evangelicals Saved by Paris Reidhead Last Days Collection Love Not the Word by Watchman Nee Humility by Andrew Murray A call to the Unconverted by Richard BaxterThese were all very good reads. Also you can't go wrong with The Christian in complete armor by William Gurnall. Very powerful. Adam
