Her younger brother, Matthew, is seriously ill with Leukaemia, so when Catherine and her new Hindu classmate, Uma, witness a strange and mysterious phenomenon in the hills, Catherine is convinced that it is a sign that Matthew is going to get better. But Uma is far from sure, and as news of the 'vision' spreads, Catherine finds that she not only holds the key to her family's uncertainties, but those of the whole community.
