You don't know what's going on in Sara's house... Or in her head. Sara is lonely. No one talks to her - not even her bad-tempered workaholic husband or her two beloved sons. Her solace is her house, the biggest in the village, hidden away behind high hedges. Then she strikes up a friendship with Katie, a college student living nearby, and a new world opens up. Her neighbours have been dying to get to know her, and they rush to help when Sara is devastated by a terrible accident.
But nothing is quite what it seems. And when new betrayals and shocking revelations disturb her peace, Sara realises she has no choice: she must act to protect the safety of those she loves.
