Simple as the title suggests. Throw as little or as much as you want in here. I'm more interested in Fiction ATM, for my non-fic list is overwhelming, but I'll look into anything you think is worth reading Fic or Non-Fic. Thanks.
The Pilgrim's Progress. It's an allegorical story of the spiritual life of a christian. I only read spiritual books, so that's all I can offer.
Have you checked out Ken Follett? Weighty tomes for sure, but the Pillars of Earth/ Kingsbridge books are excellent as is the Century trilogy, loved them.
