'I wish I wasn't the weirdest sixteen-year-old guy in the universe.' Felix would love to have been a number. Numbers have superpowers and they're safe, any problem they might throw up can be solved. 'If I were a five, I'd be shaped like a pentagon ... there'd be magic in my walls, safety in my angles.' People are so much harder to cope with. At least that's how it seems until Bailey Hunter arrives at school. Bailey has a stutter, but he can make friends and he's good at judo. And Bailey seems to have noticed Felix: 'Felix keeps to himself mostly, but there's something about him that keeps drawing me in.' Both boys find they're living in a world where they can't trust anyone, but might they be able to trust each other, with their secrets, their differences, themselves?
