When a baby is kidnapped in broad daylight with no witnesses, an otherwise sleepy suburb is rocked by scandal and ten-year-old Flora Lanyon is terrified.

As strange and unexplainable occurrences start to happen, Flora grows increasingly suspicious. What dark secrets are hiding in the house? Is Flora safe there? And can she unearth the truth before the past catches up with the present?
