Truckers by Terry Pratchett

Truckers is the first book in Terry Pratchett's Bromeliad Trilogy, which is geared towards a children's/YA audience. This was only the 2nd Pratchett book I've read, and I enjoyed it just as much as I did Going Postal. 

The book begins with a group of nomes who decide to abandon their Outside habitat in favor of something safer. They hitch a ride on one of the trucks that they have watched and end up inside the Store (Arnold Bros. (est 1905)). What ensues is basically a parody of the early Church, and it is delightful. I need to obtain a copy of Diggers, the next in the trilogy. Perhaps I'll luck out on my trip to Half Price Books this morning.

This will fulfill my "P" author in the A-Z challenge (the completion of which is looking quite grim...)
