An old house can hold many secrets. Hollowpark in the west of Ireland certainly does. At the heart of the gardens is an intricate maze, named after a deadly poison, Belladonna. If you know the way through, it's magical, a hiding place and playground like no other. If you don't, it's a place of fear and sinister riddles, where a young girl once went missing and was never seen again.

Grace comes to Hollowpark as a nanny for young Skye FitzMahon. Soon the mysterious past of Hollowpark has seduced her. Who is the woman she sometimes glimpses in an upstairs window? Or the apparition who keeps showing up unexpectedly, pleading, 'Find me'. And how can she fight her growing attraction to Skye's father?
