Here are few I have read twice or more.

"A Species of Eternity" by Joseph Kastner. Reading it now for the third time after having found this out of print book on-line. (Previous copy stayed with the ex in the property settlement *smile*.) It is about the early New World naturalists - Colden, Banister, Lawson, Bartam, etc.

"The Best of the West Virginia Hillbilly" Jim Comstock (may his curmudgeonly and comic, sharp witted soul rest in peace, even if he was a Republican:>)

"A Distant Mirror: The Calamitous 14th Century" Barbara Tuchman

"Bodyguard of Lies" Anthony Cave Brown (Allied espionage and the resulting smoke and mirrors to conceal preparations and plans for D-Day.)

Most of E. B. White's books.

Several of John Steinbeck's novels.

A slew of books I read for the first time between the ages of 11 and 25. I had the vocabulary and the basic intellect to enjoy them at the time, but not the life experience to fully appreciate their richness and complexity. would certainly include several of Steinbeck's novels, a few by Hemingway, and "To Kill a Mockingbird" among them.

"Fair and Tender Ladies" Lee Smith

"A Place to Come To" Robert Penn Warren
