Publisher's summary[]

Many years ago, when she was travelling with the Doctor, Jo Grant visited Zayin Eight. Now, suddenly and inexplicably, she is back on that ravaged planet, and reunited with a human called Newton Calder. What happened to the missing members of Calder's team? What is the secret of the vast ruined city? The answers will lie in the dark and distant past of the Time Lords themselves...
