Alternate history done as 'literature'. Intriguing idea that's chilling with well thought out details of how America could have launched it's own anti-Jewish program in the '30s if things would have been slightly different. The descriptions of the how the persecution begins and acclerates seem very plausible and scary. However, the ending seems ridiculous due to an outlandish plot twist that jars compared with the realistic nature of the rest of the book.
