'To lose one set of memories may be regarded as a misfortune. To lose two smakes of carelessness.
The Terran colony world of Espero seems the unlikely source of the sophisticated distress call. And the Doctor, Fitz and Trix are not the only ones responding to it.
While Fitz consorts with royalty, the Doctor's on the run with a 16-year-old girl, and Trix meets a small boy eith a dark secret.
In a race for the minds and souls of an entire planet, the Doctor and Trix are offered temptations that may change them forever.
At least one of them will be unable to resist.
