I loved the Killer Angels. If you really want a complete understanding of Gettysburg, try this: http://www.amazon.com/Gettysburg-Invasion-Allen-C-Guelzo-ebook/dp/B00A9ET69I/ref=dp_kinw_strp_1 Heavily researched, it's the first book on Gettysburg I've read that was filled with page after page of new persepctives. I love "Killer Angels" (although technically it's historical fiction), but "The Last Invasion" puts everything into perspective in a way no other book I've read on Gettysburg has ever done. Joshua Chamberlain, although still a hero in my eyes, maybe wasn't as much of a hero as he's been given credit for--this book makes it clear who did what, and when. Despite the amount of information given, it's well written, with many interesting side stories, almost reads like a novel.
Been through a bunch of books lately.. Best book I've read in the past few months: "The Boys in the Boat: Nine Americans and Their Epic Quest for Gold at the 1936 Olympcs", Daniel James Brown. I have absolutely no interest in rowing whatsoever, but this book passes on the excitement of the sport, race after race concisely. But it's only a backdrop for the book: A great life story set in a great athletic story set in hard times intertwined with what was going on in Nazi Germany. This book was crafted more than written and it shows, it's impossible to put down. "Undercover and Alone" was very good--my wife really liked that one as well. Definitely worth picking up. "Saturday Night Live: A Backstage History of Saturday Night Live", Doug Hill, very interesting and enjoyable read for those who grew up on SNL. Those are the best of the bunch I've recently read I also now own a Kindle Voyage, which I like mainly because of portability, and a Kobo H20, which hands down is the best ereader I've come across. It has a larger and more natural looking screen than the Kindle, it's great for reading at home. Both are pricey, and if you like a smaller screen, the latest Kindle Paperwhite is the biggest bang for the buck.
