Doctor Who: The Awakening (The Doctor Who Library, Book 95)

The Doctor and his companions, Tegan and Turlough, are on their way to a pleasant visit with Tegan's grandfather in 1984. However, upon arrival, it looks like everyone the meet is dressed for the 17th century. Turns out the town is going to reenact a battle from the Civil war. However, something is wrong (isn't it always when the Doctor is around). Tegan's grandfather is missing and strange things are afoot at the old church. And the reenactment is turning into a far more serious and deadly affair than most of the villagers thought. Oh, and the vargaurd force of an alien invasion is driving the town's leader into madness. Can the Doctor help? Or will evil win the day? Lots of action in this one, with a higher page count than most of the Doctor Who novelizations. Still a quick, fun read though!
