Lily Emmett has suffered from selective mutism since childhood and still struggles to see the value of everyday speech. Her sister, Connie, has always spoken for her, and her partner, Richard, has learnt to translate her movements so that they share a unique form of communication. But when the two sisters return to their childhood home after their mother's death, the visit inspires memories of the event that first rendered Lily silent, and still haunts them both. The resulting search for the truth about what happened takes them back to a childhood shaped by bullying and familial breakdown and unearths the secrets that lie at the heart of the sisters' relationship. Hush is the fantastic debut novel of Sarah Marshall Ball.
