Swiss Chase

Genevieve and Andrew are British children happily living with their scientist parents in Switzerland. Suddenly one night they find themselves being bundled out of bed by Nanny Claudia, as a gang of men surrounds the house. They break through the circle but Claudia is captured. What should they do now, and who are these men. What is going on?
Join Genie and Andrew on an epic trek across the length and breadth of Switzerland as, by water, air and foot they attempt to avoid capture and discover what has happened to their parents; and also why the gang is so keen on trapping them. What is it they have that is so important for them to be pursued so desperately?
As they meet different characters on their travels how will Genie and Andrew know who they can trust and who they can't. Can they trust those closest to them? Can they even trust themselves?
