Two Weeks with the Queen [EPUB ebook] 

A humorous but deeply moving story about Colin who refuses to believe that his younger brother is dying of cancer and decides to take things into his own hands. Colin decides to go to the top for help, none other than the Queen. Colin’s efforts to penetrate the British establishment are hilarious, surprising and doomed to failure, but although Colin can’t find a cure for cancer, he does find a way to help some of the new friends he makes, as well as discovering the best thing he can do for Luke.
