Wooden Heart is a BBC Books original novel written by Martin Day and based on the long-running science fiction television series Doctor Who.

Martha and the Doctor discover an apparently deserted starship, and soon, a village appears in the middle of the craft.

Whilst exploring they find a fully populated village and forest, whose inhabitants appear to be unaware of the spaceship outside, and whose children are mysteriously disappearing.

Later, The Doctor and Martha find a creature from another dimension, who, because of its telepathic powers, was used to remove the evil from prisoners in the Castor.

The Doctor offers to pilot the ship closer to a sun to give the creature more power to run the program, and a woman from the village absorbs the evil into her body, before exiling herself, so she can learn to control it.
