Being a teenager is hard enough, but it's even harder in a world you've never known ... Eighteen months ago, 17-year-old Rose and 13-year-old Rudder escaped a strict religious sect with their mum. They are still trying to make sense of the world outside - no more rules about clothes and books, films and music, no more technology bans. But also no more friendship with the people they've known all their lives, no community and no certainty. It doesn't help that their mum has to work all hours to pay rent on their cramped, smelly, one-bed flat above a kebab shop in Hackney.
