The Dragon River Adventure

What if some of the myths and legends were true. Like if King Arthur had been a real person would that mean Avalon is a real place? And if you owned Excalibur would you have to call the British Royal family every time you got it stuck in a stone? Also, if dragons existed would they speak English? How would you go about riding one? And what would they do with the internet? These were questions eleven-year-old Tyler Tremain had never bothered to ask. He wanted to know where the next meal was coming from and whether his mum would be able to scrape enough money together to get him a school uniform before term starts. Then his mum accepts a mysterious job in the wilds of Wales and his life changes in ways he could never have imagined.
