The Empty Room - Brooke Linford

Emily and Mark have a perfect marriage, but they long for a baby.

As infertility begins to take its toll on Emily, her world is thrown into chaos with the arrival of a beautiful new colleague, Victoria. It's only small things at first: the painted-on smile, the lingering stares at Mark, the intrusive questions. But things soon escalate, with random deliveries, an encounter with a brown snake, and a suspicious death.

As a bushfire rages nearby, the threats pile up, and Emily becomes overwhelmed. Is Victoria as dangerous as she suspects? And why will no one believe her?
