It feels wrong to recommend a book I haven't read yet, but Chuck Wendig's "Zeroes" might be a good book to pair with Scalzi. I expect from his other books and the reviews that this is going to be more of an adventure book than any hard-computer-science... But, again, that might be what you're looking for. On a similar note, its been a while since I've read them, but I rather enjoyed James Strickland's books, Looking Glass and Irreconcilable Differences. Part of that might be because there's a part where he explains IPV4 addressing, and the example he uses happens to be the Class-B where I grew up. It was a little like seeing your house in the background of a movie. I also sort of enjoyed Rick Dakan's "Geek Mafia", but that appears to have fallen off the planet; only the sequels are on Amazon right now...
