Lucy has a lovely husband, a job she adores as a teacher, and a house on Mulberry Avenue that she’s decorated just the way she wants – from the floaty curtains and the softest bed linen, right down to the perfectly-chosen velvet cushions on their comfortable sofa. Life isn’t perfect, but it’s pretty close. She’s also got Amber. Her newest friend and neighbour. They’ve got so much in common. Even if Amber’s life sometimes seems a lot more glamorous and exciting, she shares Lucy’s down-to-earth sense of humour, and Amber seems so interested in Lucy and her life, it’s like they never run out of things to talk about. But then Amber starts acting strangely, claiming her life isn’t all it seems, talking about how she thinks she might be pregnant, and confiding in Lucy that she’s started getting threatening messages. She’s scared, and the only person she can turn to is Lucy. She wants to stay at Lucy’s house until things calm down. Lucy wants to protect her friend. But can she really trust Amber? Because sometimes other people are not all that they seem. Sometimes they have secrets. And they’d do anything to keep them…
