Darknet Diaries is moderately engaging - but overly dramatic. They also dumb things down a bit (I assume to attract a wider audience?).

I still find myself listening occasionally, so it's hard to criticize too much.

I'm a big fan of Countdown to Zero Day. I've recommended it to a lot of non-techie friends as it's a great blend of pacey thriller with just enough information to help a non-techie understand some basic elements of a sophisticated malware campaign.

Just an aside, I have met Kim a few times at various conferences. She is an interesting person, in a good way. She came to the book as an infosec neophyte. We talked about her process as something of a technologist outsider and how she decided what to focus on. Ultimately, she decided the storytelling was far more important than the technical details, though she felt those were incredibly important as well.
