The Chronicals of Lake Narocz by Mieczyslaw Lisiewicz, 1945, published in full with extensive (and growing) commentary and additional background material. I have spent several years, on and off, transcribing the work, picking up new snippets of information along the way, including an email from Lisiewicz's daughter telling the remarkable journey across war-torn Europe that the author's wife endured, carrying the manuscript with her.
