M.I.C.E. and the Dragon Worm

As summer holidays begin on the North Yorkshire coast, a destructive computer worm attacks the country, spreading rapidly round the world and bringing civilisation to a standstill. Where does it come from and why? Governments are baffled. The ancient secret organisation called M.I.C.E. asks Olly and Tilly to investigate. Soon they, two friends and a crack team of talented animals and birds are in a race against time to trace and destroy the worm, facing a ruthless enemy and deadly dangers that test them to the limit and beyond. Half a year earlier, while battling evil foes from the past, Olly and Tilly discovered their special abilities with a mysterious black stone passed down in their family for centuries. Now those abilities are needed more than ever. Of course, this time it’s nothing to do with the past – is it?
