I think the best kinds of books are the ones that impart knowledge that make you put them down for a few seconds every now and then to let what you have read just sink in :)

100% agree. The un-putdownable books are ok for a while, but the ones that make you think are the ones that leave an impact on you. Same for music, the dancy songs are great entertainers, but the ones which make an impact on your life are the ones which have a soul in them :)
