Told from two different points of view, this action-packed story begins when Jackson's mum, a professional singer, whisks him away to a new home in the suburbs after she witnesses some unusual business at the casino where she used to work. Narrator Stig Wemyss takes on the chapters from Jackson's point of view and quickly establishes a rapport with listeners with his plainspoken and unrushed performance. Jackson is a numbers freak, and Wemyss portrays this obsessiveness with grace. Rebecca Macauley performs the chapters from the perspective of Esmerelda - Jackson's new girlfriend - with equal vitality. Wemyss and Macauley work smoothly together to build nail-biting suspense as danger arrives to threaten Jackson and the people he cares for.
I think the best number in the whole universe is eight. My friend, Asim, likes numbers about as much as me, but he likes them all - odd or even. Esmarelda, though, who lives across the street, isn't so fond of numbers and she hates math. Singing's more her thing. She's really good, too - nearly as good as my mum. Mum's a professional singer, or was, until we had to move. The worst number in the universe, though, is seven. For a start, it's an odd number, and it's thin and sharp and mean-looking, like a medieval scythe. So when I saw 777 on that Mustang's license plate, I knew it was the start of something bad. And I was right.
