Wild moose chase - Siobhan Rowden

A hilarious adventure story for fans of John Boyne and David Almond's
younger fiction.
Twins Bert and Camilla are in competition with each other about everything.
So they jump at the chance when they hear about the ultimate
competition that will guarantee just one person eternal glory.
The Queen wants moose cheese. Moose cheese is scrumptiously delicious,
worth an absolute fortune and near-impossible to make. It'll
require a dangerous world-wide venture to collect the ingredients
for the Queen, but nothing will stop the twins.
