I'm fairly steaming through these; at my reading speed, I can basically get through half a Who book on each leg of my commute. (I'm not working tomorrow or Monday, though, so you will be spared for the next few days.)

( 33) Doctor Who - Marco Polo: Lucarotti's best novelisation )
( 34) Doctor Who and the Keys of Marinus: Uneven but a decent effort )

I've already read Doctor Who - The Aztecs, so next up is Doctor Who - The Sensorites. Next week.
