En route to England with her father, 13-year-old Isabella meets a young European, Leo, travelling with his Aunt Helena. Isabella senses a mystery and soon finds out that the two are political refugees from Domeria. In London, Aunt Helena is kidnapped, and Leo is on the run. Isabella and her father are soon ensnared in a complex web of international espionage and intrigue.
Set in both London and the spectacular mountainous (and fictitious) country of Domeria, this fast-paced adventure story deftly combines a lightness of tone with a broad spectrum of serious issues, initially inspired by the events of September 11.
