Here are the three Laws of Quill, carved in stone outside every town hall, and learnt by every schoolchild: There shall be No Witches. There shall be No Dragons. There shall be NO SECRETS. Ten-year-old Brim has been sent to the Quillian School for Prevention of Witches, but she's sure it's a mistake. It's true that she has tiny feathers sprouting from her elbows, and that she's the only person who remembers the odd-looking calf that has been following her. But she is most definitely Not a Witch. Meanwhile, Queen Rose of Hallow has received reports of a secret weapon in the mountains of Quill, and goes to investigate. Alone. Luckily, she's not just a twelve-year-old girl with red hair and a wilful nature. She is also a dragon. Before long, Rose and Brim find themselves trapped in Quill, in the worst possible danger. Just a witch, a dragon and a LOT of secrets.
