won the 'Carnegie Medal' in 1969 for 'The Edge Of The Cloud', the sequel to 'Flambards'.

I was runner-up for it for 4 years before then, including being the runner-up in 1966, the year it wasn’t awarded! As the prize is for the best children’s book of the year, how could it not be awarded? I was also runner-up with another book the year I won it.
