The novel “The Taking of Chelsea 426” by David Llewellyn was published for the first time in 2009.

When the Tenth Doctor arrives on Chelsea 426, a space colony orbiting the planet Saturn, his first impression is of a rather boring place with rules that prevent fun. The Flower Show is a local event but the Doctor’s attention is drawn in particular to a strange plant discovered in space.

The Doctor tries to examine the mysterious plant before the show opens but without success. His investigation is interrupted by the arrival of a Sontaran spaceship on a special mission commanded by intelligence General Kade.
