Her Brother

Olivia is 16 and her parents go away for their 20th Wedding Anniversary to Paris for a week and, as they don't trust Olivia to stay home alone, they take her to stay with their friend, Anne. Anne has two children Gemma, 20, and Harry, 19. Olivia vaguely knows Gemma as she used to go to the all girls school that Olivia currently goes to but she has never met Harry, until now.
