Two Weeks with the Queen hardcover educational edition by Morris Gleitzman
At first, Colin thinks it's all the turkey and Christmas pudding that has made his brother, Luke, ill when he collapses on Christmas Day. But when his mum announces that Colin has to go to England to stay with his Aunty Iris, it's clear that things are more serious. Then he hits on a plan: who better to help him to save his brother than the Queen?
