Nominated for the Carnegie Medal. Longlisted for the Branford Boase Award. Aidan needs his bike to deliver all the mail his postman dad's been hoarding since his mum was sectioned. But his bike's just been stolen. In the early morning, Aidan chases after the thieves, hellbent on getting it back. When he reaches the abandoned factory where they've stashed his bike, he has moments to grab it and escape. But he finds more than just stolen goods. There's a mysterious prisoner chained to the floor. This is the story of why Aidan goes back. Recalling Alan Garner and Susan Cooper, Why I Went Back is a dark tale of magic, myth and undelivered mail.
