The Porpoise | Mark Haddon
A motherless girl grows up in isolated luxury, hidden from the world by her wealthy father. She believes their life together is normal - but as time passes, she has a growing sense that something between them is very wrong.
She cannot escape, so she seeks solace in her books. Her favourite tales are those that conjure ancient worlds - of angry gods and heroic mortals, one of whom will some day come to her rescue. Soon, she will forget where the page ends and her mind begins.
