January Books 20) Pest Control by Peter Anghelides
I somehow missed this when it first came out back in 2008 - the very first New Who original audiobook, a story that was never published in hard copy, but just read by David Tennant on two CDs. It's actually very good, with Tennant doing all the voices - his Doctor, Donna, various other characters including a centaur with an Ulster accent - and narrating in his native Scots burr. I thought the story was a notch above average - centaurs and humans are fighting, but giant insects and huge robots make an appearance too, and there's some consideration of body shape and destiny, and telling the truth. Glad to have caught up with this at last.
