Query: Too boring to finish

I love *good* historical fiction - I've reread Patrick O'Brian's Maturin/Aubrey series many a time. But this story just didn't hold my interest. I particularly disliked the format in which it was told, in which someone "off screen" occasionally interrupts the book.I've read some of Turtledove's other alternate history stuff, and I think he simply isn't that good at creating interesting characters. Instead, as we read the alternate history, we're interested by comparing/contrasting his world to ours.In the end, I stopped reading the book about half way through because I simply didn't care about the story or the characters.
