A touch of magic hit historic Alnwick Castle yesterday as a book about another heroic young Harry was launched.
The lad in question wasn't Potter, but young Harry Hotspur - the subject of a Hexham-schooled author's debut novel.
AL Williams was at the castle yesterday to launch her first children's book, Knight's Quest, with knights, dragons and jesters in attendance.
The castle itself features in the novel, which recounts the exploits of one of Northumberland's most famous heroes.
Knight's Quest tells the story of the ghost of a young Harry Hotspur returning to the castle to battle a monstrous, fire-breathing dragon and break a curse that has fallen on Northumberland.
The teacher, who now lives in Leicester, was inspired to write the book after reading an article in The Journal discussing children's lack of knowledge about the charismatic warrior who went into battle at eight and was knighted at the age of 11.
And yesterday, the book was brought to life at the castle with a full day of knight's activities, including swordplay, birds of prey and a jester.
Ms Williams, at the castle for the launch with illustrator Sylvia Lynch from Stocksfield, said: "I'm absolutely thrilled.
"I have to keep pinching myself to believe it's all real.
"It's been an absolutely fantastic day at the castle, the kids are all dressed up as dragons and knights and there are sword displays and falcons around us."
