Sometimes things lurk below the surface which only the Doctor can see...

3.1 The Seas of Titan by Lizbeth Myles
Out on Saturn's moon, Titan, an outpost all-but-forgotten by Earth struggles on against the odds.
As the Doctor joins explorers deep in the methane seas, they discover a hidden civilisation. But will the Sea Devils prove to be the colony’s salvation or its final destruction?
