New BJJ books for vacay

So, between the laying on the beach and the traveling time I figured I needed a good sampling of reading materials. I hit the bookstore, and with some quick internet hits to slideyfoot's reviews I purchased:
(the links are to slideyfoot's reviews)
The Guard (Brazilian Jiu-Jitsu Details and Techniques)
and
Passing the Guard: Brazilian Jiu-Jitsu Details and Techniques: Volume 1
So, thanks for the good reviews as always. They helped me make the purchasing decision to put out over $70 for both books. But I won't be without a jits fix.

I also decided to get a classic Sci-Fi book:
Foundation, Foundation and Empire, Second Foundation by Asimov
I know, I know, I am a software engineer and Sci-Fi fan and have come this long without reading Asimov. Hey, I did read all 53 Dune novels and I own all BSG on DVD so back off. ;) This is a good size book for the beach. So, now that I will be plenty mentally stimulated I think I'm ready to go.

Also looking at taking the next PADI cert, Advanced Open Water Diver.
