Seriously. This thing had me sitting forward in the Cruiser seat, my face practically shoved into the windshield and purposefully slowing down lest we reach our destination before the fourth cd ended. The last audiobook that had me this entranced is Malcolm Gladwell's Blink: for the first few chapters of that, I was so riveted that I didn't realize one of our bikes had come off the rack and was hanging by its lock, its rear tire dragging along I-376. This shit is dangerous.
Huge thanks to C and E for the reco.
