I don't do iTunes for anything except the minimal apps on my iPhone. And if I had found a viable alternative to an iPhone, I'd have already switched. But much as Apple and the iWhatever annoy me, I have to admit that the iPhone gets the job done and EVERYONE builds apps for it.
I'm just starting #2,
The Disciple of Las Vegas, so I have a day or two for someone at Kobo to wake up and fix this egregious anomaly. Not that I'm holding my breath. Unfortunately, the Library doesn't carry the eBook version, and I'm just not going to do paper books any more if I can reasonably help it.
I also see that he claims the audio version of the books is available on Audible, but I'm not seeing it, either in Canada or the US.

Downpour has it, but I'm not likely to spend >$20 on an audio version when I won't spend $11 less a 40% or 50% coupon.
