It would make a nice gift for any church history buff: On This Day in Christian History: 365 amazing and inspiring stories about saints, martyrs, and heroes, by Robert J. Morgan.
Littering the pages also are folks such as Simeon, a monk who spent thirty years atop a tall pillar, and Elizabeth Hooton, a Quaker preacher. Morgan doesn't seem to be overly choosy in his inclusion of religious figures; however, it certainly does make for some interesting reading. I could imagine a pastor or inspirational speaker would find it especially interesting, both for general knowledge and for illustrative use. The book also includes an index of selected topics, a handy resource for such purposes.
