Is "tour de force" too strong of praise? I don't think so. Wow. I did not expect this book to be as excellent as it was. Such a great read. If you've ever read time travel fiction before and liked it even a little bit, please give this one a try - you will not be disappointed. So richly detailed, so thoughtfully developed -- not a jot or tittle out of place. The author draws one in with her sympathetic character, then throws her under the bus and we can just bite our nails and hope that she comes out alive. Really an amazing work of fiction. Bravo.
