Query: Outstanding!

Turtledove has written an engrossing, devouring tale of an alternate history. This series has (so far) been far superior to his other works such as "How Few Remain" because most of the characters are fictional or mostly fictional so he is much less limited in character development. Of course, there are many (too many?) subplots, the depth of detail and breadth of vision of Turtledove in this series is remarkable. The most surprising aspect of this series to date has been his sense of humor and sublety. For example, 3-Finger Mordecai Brown makes a subtle cameo appearance, and (not to give too much away), when the AMERICANS bomb Pearl Harbor, a casually tossed in line about "this day will live in infamy" is too rich to pass up. Outstanding.
