This is How You Die: Stories of the Inscrutable, Infallible, Inescapable Machine of Death
This was one of my favorite Doctor Who novels so far - the characters are well-realized, the plot is interesting and I could actually tell the supporting characters apart. I really enjoyed the way the mystery unraveled and how it was solved. There are some really nice little character touches in here, too, making it feel very much a part of the Doctor Who universe.
