You will want to know a bit about this book before you commit to reading it. This novel is about two very different girls growing up in a tough Yorkshire town in the 1970s - spoilt Gemma, who seems to have everything, and neglected Pauline, who has less than nothing. But that is not the only story. A tale of penny sweets, suburban back gardens, swimming trips and Butlins holidays makes way for something altogether more sinister. And it is this story that will pull you towards its unimaginable climax, leaving you - haunted? Heartbroken? Angry? This is the story that won't let you go. This is the story you won't be able to forget. This is What They Do in the Dark.
