All goods books I am sure, men. I've read 'Imitation of Christ' and 'Secret of the Rosary'.
I highly recommend reading Confessions of St. Augustine if you have not done so already. I can understand why some Catholic authors have written that if you were forced to choose between the writings of St. Augustine or all the others Saints, Fathers, Doctors, Popes, theologians, etc. combined I would choose St. Augustine.
