It won awards, got turned into a TV show and even had a very good band named after it. The back cover blurb states:
Winner of both the Guardian Award and the Carnegie Medal, this is an all-time classic, combining mystery, adventure, history and a complex set of human relationships.
It all begins with the scratching in the ceiling. From the moment Alison discovers the dinner service in the attic, with its curious pattern of floral owls, a chain of events is set in progress that is to effect everybody’s lives.

“This book is a superb piece of architecture in which every detail plays its proper part.” Growing Point
