Ah, that's fantastic! Thanks for letting me know :-)
I've been mostly listening to the main novels on Audible, but didn't see the point of expending one of my monthly points on an audiobook that only lasts a fraction of the time of the others. If they did these as an anthology on Audible that'd be a definite sale.
