So I really liked this one but only because Twain somehow pokes fun at each gender equally.
Adam's section is really the humorous part of the book; Eve's diary is the philosophical portion of the book (although of course it has its humorous moments) adding context to Adam's self-pity.
The book is short--you can read it easily in an afternoon. Get it if you want a light-hearted view of men and women.
My favorite line is the last line of the book, probably because I am sentimental and mushy when it comes to love: "Where ever she was, there was Eden."
