The Elegant Universe - Brian Greene. I'd second that - even I understood a lot of it, and I'm no physicist! It's important to remember that we're talking theory not fact at this level, though, and Greene has his critics.
Personally, what I'm looking for is someone who can take my day for me and wrap it up in lots of other dimensions, so I have the same length day (I like my sleep!) but can achieve an awful lot more within that time. If anyone comes across any literature on that (or better still, an invention that does it without my even having to read about it) please let me know!
