Gift and Mystery by JP2 (the Great)
Virginity by Raniero Cantalamessa, OFM Cap. (JP2's retreat preacher)
--- i read those... very good.
"No Man is an Island" -- Thomas Merton
"Merton and Sufism"
"The Passion of St Therese"
"The Spiritual Writings of St John Bosco"
"Divine Mercy in My Soul" - St Faustina
"The Sexuality of Christ in Renaissance Art and Modern Oblivion"
=== Very good book analyzing art based upon theology and theology of the body. I know it sounds a little strange, but if you are and art buff and like theology it is worth a look.
