I've always been a fan of anything by Allan W. Eckert.

These stories to me, are America's mythology. Tecumseh, Daniel Boone, et cetera. Even though it's history, it's unfathomable to me to grasp that this stuff actually happened, especially what happened in my home state Ohio, it feels like it's mythology, even though it's the truth. Anyway, the historical Native Americans and the New Americans who were forever expanding west for a new country, are equal in respect and fascination to read. I just love this stuff!
