In THE WILD TREES, Richard Preston unfolds the spellbinding story of Steve Sillett and Marie Antoine, who found a lost world above California, dangerous, hauntingly beautiful, and unexplored.
The deep redwood canopy is a vertical Eden filled hanging gardens of ferns, reefs of lichens, small animals, and all sorts of plants, including thickets of huckleberry bushes and small trees actually growing on the branches of giant redwoods. There are massive redwood limb systems fused into flying buttresses and carved into “fire caves.” Thick layers of soil sitting on limbs harbor animal and plant life unknown to science. Humans move through the deep canopy suspended on ropes, far out of sight of the ground, knowing that the price of a small mistake may be a plunge to one's death.
Preston account of this world, by turns terrifying, moving, and fascinating, is an adventure story told in novelistic detail by a master of nonfiction narrative. Preston became an expert tree climber, and learned the techniques of super-tall tree climbing to tell the story in THE WILD TREES—the story of the fate of the world's most splendid forests and of the imperiled biosphere itself.

It's a social history of the later Roman Empire from Constantine to Justinian, with an emphasis on the Christian Church and changing attitudes towards wealth, charity, and the poor.
Any book on Late Antiquity by Peter Brown is a good read. Light reading it's not! Then again, I enjoy stuff like that and find light reading boring.

In the world of the books, Harry Dresden is Chicago's only wizard private detective--think Harry Potter meets Sam Spade. And there are 14 of 'em, so they'll keep you busy for a while at least.
If you haven't signed up for them yet, think about getting on the mailing lists of Power Reads, which is mostly non-fiction, and they're often sale priced or even free. There's also Pixel of Ink, which has free and sale-priced books across a broad range of genres. I've picked up quite a few books from both sites.
for the info on "Power Reads"...will check it out.
I already get Pixel of Ink. Lots of great deals there.
PS...another site I just remembered is Ereader News Today. Lots of discounted and free books there as well...
