If you want to begin praying the Psalms this Lent, let me suggest a great little book–My Daily Psalms Book: The Perfect Prayer Book. This little prayer book has all the Psalms organized like they are when prayed in the Divine Office–they are organized by day as well as time (Matins, Lauds, Prime, Terce, Sext, None, Vespers, and Compline). This would be a good introduction to someone wishing to pray the Office, but maybe not having the time yet. You could at least get into the habit of praying the Psalms of the Office.
