this is a great book. like the swallows our son ollie came in the spring and left in the autumn. ollies story is one of extraordinary courage and overwhelming spirit.without warning at the age of two ollies young life was turned into a baffling challenge by autism. at the age of four ollie and his family faced a new an unimaginable menace when he was diagnoised with leukaemia. its a must read book but very sad.
