My god. I like other conroy books (1945, Red Inferno was brilliant IMHO), but this book sucked from page 1. No interesting characters, just top-brass talk, and the action that happens is a little black-and-white and not interesting.
What is worst: the Union not only wins despite the Brits entering War on the Confederate side, but wins within 1862 instead taking longer for it. The Confederates, in real life brilliantly led by Robert E. Lee, in this book run around like Zombies, or Orks, or something, they watch the Union shift armies from South to North, beat Brits, and then turn South before Lee does anything. The Rebels still look ragged despite the British Navy breaking the see barricade of the Union, and in reality the Brits, despite being the Number 1 World Power back then, are no help to the Confederates. And the Confederates even stop building their technology programmes (warships, for one), why should they?!?
I really flew over the last 50 heroic pages because it was clear that the Union would win without effort.
Boring read, sadly.
