Nowhere on this product page does it say that this version on audio CD (read by Alex Jennings) is an abridgement. So, I assumed it was unabridged. Then I receive the audiobook and notice in small writing on the bottom of the box "Abridged by Martin Plimmer".
I only like to listen to unabridged recordings, so it kind of made me upset. I hope my message here helps others wondering if this is abridged or unabridged.
Specifically, I am referring to ISBN: 978-1934997604.
