Tanglewreck. Jeanette Winterson

But Time is big business, and whoever gets control of Time controls life as we know it! In a house called Tanglewreck lives a girl called Silver and her guardian Mrs Rokabye. Unbeknown to Silver there is a family treasure in the form of a seventeenth-century watch called the Timekeeper, and this treasure holds the key to the mysterious and frightening changes in time. When Silver goes on the run to try and protect herself and the Timekeeper, a remarkable and compelling adventure unfolds, full of brilliance and wit, as is befitting an author with the imagination and style of Jeanette Winterson.
