Pretty good. A little long-winded, but maybe that's because I went for the large-type edition, to avoid the long queue for the regular version. He has an annoying last name, hard to remember how to pronounce. Shay-bun. The internet says that this has been verified by his publisher. I guess Moonglow is a fictional memoir, or an autobiographical novel. There was a time when I would have cared to find out. Now, I'll just wait around until I hear it second-hand.
Longer, and more tedious, than I remember when I read it in high school. The love affair is the most interesting writing -- and it's all being set-up for the (much shorter) interrogation/torture scene.
