Ask HN: Good ways to record an audiobook for my nephew?

My nephew's birthday is coming up. I plan to record for him The Phantom Tollbooth, a book I loved around then.

I'd love tips from HNers who have recorded audio or audiobooks on the best way to go about it. I'm on Linux, and to listen he could borrow iPad, iPhone, or Android phone from his parents. (I'm glad to buy some physical device as well if that's helpful.) But please mention other platforms if you have experience, so that this thread is good for others with the same interest.

The things that I know to wonder about: performance tips, ease of editing, thoughts on audio quality, best way to record it so that they can easily listen one chapter at a time, and options for including illustrations (if I want to take it that far).

But I'm especially curious about the things that I didn't think to ask, things that I will wish I had considered before recording many hours of audio.

Thanks!
