The South East District of The Evangelical Free Church of America has produced some quality book summaries.
I ran across them when looking for information on The Leadership Pipeline by Charan, Dotter and Noel but there are also reviews of many modern books as well as some of the great classics.
Check it out. These resources might be valuable for your own learning but also useful material for study groups or eldership meetings.
