A vote for Mary's books
I am reading "Replaceable You" by Mary Roach aloud while Lynn does jigsaw puzzles. Mary's books are unusual, witty and informative. "Replaceable You" covers parts of the human body that get replaced, sometimes successfully and sometimes not. "Bonk" is about human sexual intercourse, that important process that made us.
I like Amazon Kindle ebooks. They are virtually weightless, immediately available, arrive as a sort of phone call. Many of my friends dislike ebooks for lack of heft or scent or simply being electronic instead of paper.
