Feel free to peruse any of the books in here at your leisure.
The Grief Recovery Handbook, by John W. James and Russell Friedman
A Grief Observed, by C. S. Lewis
Surviving the Loss of a Love, by Melba Colgrove et alia. (The subtitle is: 58 Things to Do When There is Nothing to Be Done)
Clinging, by Emilie Griffin. One of the best I've ever seen.
Letters To Malcolm: Chiefly on Prayer, by C. S. Lewis. The best. I reread this one frequently.
