Martin’s got a secret. He looks pretty normal. He’s got a pretty normal job. He works in IT. He plays badminton at the weekends. Sometimes his back hurts. He’s had a pretty normal life. Until one lunchtime, in HMV, with his sandwich, he heard a sound that changed him forever. Now he’s falling down a rabbit hole of wires, words, and mysterious birds. And that’s not good for his back.
