The bigger they are, the longer it takes to read them, and the more time you can spend in the beautiful world they've invited you into. You know how you hate it when a really great book is coming to an end, and you're sad about it? Read a big book and you can put that off for a long time. Need to zone out from a lot of people, or keep yourself entertained on a trip? Big books to the rescue. If it's a good one it will do the work of three. You like them big and that's no lie.
