The Unbound Universe was the third anthology in the The New Adventures of Bernice Summerfield series.
Publisher's summary Edit
Bernice and the Doctor land on a planet so dull no one ever bothered naming it. Finally something interesting is about to happen here.
Tramatz is an idyllic world – the rivers hum to themselves, unicorns prance through the emerald forests, and, at the very corner of your eye, is a horrible secret.
The Last Song has been sung, and the final days of the universe have begun. Everyone flees to the gateway – to find that The Emporium At The End is having a closing down sale.
