I listened to the audio book and must state that it's very involved and not really for the layman like me. I got lost on the eukaryotes explanation which lost me for much of the other topics.
I've found audiobooks (and podcasts) to be great for lighter reading, but I tend to drift in and out. That's not a great system for something more scaffolded like a textbook where you have to thoroughly understand each part in order to build the next piece on top
As someone who is severely dyslexic: basically the only way I can consume large amounts of written content in an acceptable amount of time is audio book. Thankfully- I'm pretty sure listening to an audio book for me is the same level of comprehensible intake as a non-dyslexic via written word. :)
