Left to right, top to bottom.

But really, I never have really been the type of person to "hear" different voices for characters or anything like that. There's typically one little, quiet narrator voice in my head that's reading the words on the page and then my own thoughts kind of floating around in the background. I try to keep that to a minimum, or at least limited to thoughts about the book.

As far as understanding, if I come to a word I don't understand I usually whip out my phone and Google it. Sometimes I'll just breeze on by if I can get the rough idea based on context clues.

I usually retain most of what I've read until I move on to the next book. If you asked me to explain the plot of a book I read last year I couldn't do it beyond the equivalent of a dust jacket synopsis. Only exceptions to that are things I've read multiple times like Harry Potter.
