I've been putting together an ebook suggestion list, and will wrap it up tonight, and post tomorrow.

And if you're still shopping, this is the last Christmas Columbine will be 20% off in physical Barnes & Noble stores nationwide. (It gets a one-year discount for winning their Discover Award for Best Nonfiction this spring.)
Most stores keep it in stock—check availability here. At B&N, should be in the Discover Great Writers bay, next to new nonfiction. Otherwise, they keep more copies in Sociology. Or ask.
The Strand has autographed copies, and ships worldwide. (And they also have it 20% off.)
