Who he is:
"Educated at Harvard, Princeton, and Oxford, MARK HELPRIN served in the Israeli army, Israeli Air Force, and British Merchant Navy. He is the author of, among other titles, A Dove of the East and Other Stories, Refiner's Fire, Winter's Tale, and A Soldier of the Great War. He lives on his farm in Virginia."
(I hate that term, "educated at...". No, that doesn't happen. Wherever in life, one educates oneself - or doesn't. Nothing against Helprin - remarkable guy, and a humble one.)
I feel Soldier of the Great War is his magnum opus, but readers may differ. If you start with him, you will want to read all of them.
