For the book, you can still download 1.4:

And all the games should still work in the new 2.0 interface too; it's an overhaul of the development environment, with backwards compatibility. (I'm updating the book now for 2.0, I edited it.)
Some great new authors working on those, and not just Scratch too, but some "real languages".
But sadly, the 2nd edition of Super Scratch will probably just be an update to stay relevant, not an overhaul.
I hope that Edmond, the author of that first edition, will write a second book, but that depends on his time. You can check out some of his other Scratch projects here: http://scratch.mit.edu/users/LEAD/
