Is someone dangerous out to get her? Or is it all in her mind?

Becky's life is almost perfect. Growing up, she could never have imagined living in such a safe, beautiful home, with a boyfriend as loving and kind as Alex, and hopes for a little family of her own. But then stand-offish Max moves in next door, and things begin to fall apart.

First, someone starts trolling her social media. Then she finds her tyres slashed. By the time she discovers the dead bird, left waiting for her like a prize, she's sure someone is after her. And having spied some strange goings-on beyond her kitchen window, she suspects that person is Max.

Frightened, Becky turns to Alex for help, but she's surprised to find that he and Max have become firm friends--and that Alex is convinced it's all in her mind. But when news of a missing young woman breaks, Becky knows she has to do something. She's sure she's seen this woman in Max's home--hasn't she?

With Alex concerned that she's losing her grip on reality, does Becky dare keep digging, knowing her almost-perfect life could shatter into imperfect little pieces?
