Fifteen-year-old Ben Smith has the perfect family, but then everything changes. Ben's world is pulled inside out, his love-life turned upside down. Three things happen: A truck collides with a bus. A plane lands in Dubai, one passenger short. There is a vicious dog fight. Ben's family circle suddenly grows by one, then by two and then by another. The sum of all these new family members should be three, right? Except everyone knows that two plus one relatives don't make three, they make trouble. It's a year of relative madness.
