Query: If you can read his thoughts...

I found this book to be tedious, and very hard to follow. The lack of quotation marks is very annoying, and makes the separation of dialog from description difficult (at least, for me). Also, as others have said, not at all historically accurate; Doctorow takes liberties that wouldn't be tolerated in others. But, because he's an "accomplished author", it's acceptable. All in all, a very tedious story, and a hard narrative to comprehend.
