Eleven-year-old Tomas has a secret friend like no other: Flicker, a dragon with glittering eyes and scales that flicker from fiery orange to ruby red. But Tomas is also having to get used to Flicker being away, now that his dragon's home is back in the frosty North. Adventure is never far away for Tomas, though - as he finds out when another dragon hatches on the dragonfruit tree at the bottom of the garden, a dragon who quite quickly decides he is sticking firmly with Tomas! Zing is a tiny dragon with oversized wings, who causes havoc wherever he goes.
