Tomas has a secret - a big secret. He has his own tiny dragon, Flicker! A dragon which grew on a very special tree at the bottom of his grandad's garden. And not only that - his friends Ted, Kai and Kat have dragons too, all grown on the same dragonfruit tree ... Having your own dragon is magical - but Tomas is also about to find out what living with a dragon is REALLY like. When the fire-breathing kicks in and you get singed every five seconds, it's like having an unpredictable volcano in your pocket. Learning to train the dragons and keep them out of trouble at school and home will take all Tomas's creativity and patience ... What is more, the dragonfruit tree is starting to look droopy and unwell. Tomas and his friends have got to do all they can restore it to health and uncover its deepest mysteries, as well as trying to work out what big secret local bully Liam, 'King of Trouble', has got up his sleeve ... One thing is for sure, life is never dull when you have a dragon in your pocket.
