Marea was born to be different - a girl born covered in the feathers of a bird, and kept hidden in a crumbling house full of secrets. When her new tutor, the Professor, arrives with his books, maps and magical stories, he reveals a world waiting outside the window and her curiosity is woken. Caught in the desire to discover her identity and find out why she has feathers fluttering down her back like golden thistledown, she leaves everything she has ever known and goes in search of the father she has never met.
