Review title: Great beginning goes nowhere
Product review: It's an interesting read for about half the book, then you begin to suspect that the author isn't going to make much with what he's started with. There is a lot of extraneous information about cross-ice travel, and a fairly irrelevant street preacher, and some fantasy segments of "crossings." But it's mainly a good idea that needed better development, a frequent downfall with science fiction.
