Over at First Thoughts, Joe Carter has posted his top 50 Summer Reads. This is a great list because many of the books are quite accessable rather than a bunch of high brow nonsense. Of the books that make Carter's list that I have read I heartily recommend:
The one book on Carter's list that I have been intending to read for years and perhaps will try to tackle this summer is Lonsome Dove. Also, I am a huge Ron Hansen fan but have not yet read Mariette in Ecstasy.
A few suggestions of my own:
The Last Stand by Nathaniel Philbrick - Just started it. Excellent so far.
The Assasination of Jesse James by the Coward Robert Ford by Ron Hansen - One of my favorite books.
The Wizard's Tide by Frederick Buechner - One of my favorite writers.
In The Beauty of the Lillies by John Updike
Blood Meridian by Cormac McCarthy - Dark. Disturbing. Brilliant.
The Forsaken by Tim Tzouliadis - Compelling. Required reading.
Witness by Whitaker Chambers - One of the most important books of the 20th century.
Institutes of the Christian Religion by John Calvin
Christianity and Liberalism by J. Gresham Machen
