The Prince and the Pauper
Interesting and clever, but it seems to be a gimmick that has been overdone in recent years (which, I'm sure isn't the case during Twain's time - but still). Regardless, I love Twain, and would recommend this. But not strongly, probably like if we were having a conversation and in the middle of our conversation you just happened to notice the book on the coffee table, to which I responded, "yeah, you should read it sometime".
