Welcome to Litsy!

"The Doctor, Romana and K9--anda young stowaway named Adric--are trapped in the alternative universe of E-Space. Seeking help, they land on an unknown planet--and find a nightmare world where oppressed peasants toil for the Lords who live in the Tower, and where all learning is forbidden--a society in the state of decay. What is the terrifying secret of the Three Who Rule? What monstrous creature stirs beneath the Tower, waking from its thousand-year sleep? The Doctor discovers that the oldest and deadliest enemy of the Time Lords is about to spring into horrifying action."--back cover.
