A gothic psychological mystery by Alice Feeney that pays homage to classic locked-room mysteries, particularly And Then There Were None.

The story follows Daisy Darker, who reunites with her estranged family at her grandmother Nana's isolated house on a private tidal island to celebrate Nana's 80th birthday. Once the tide comes in, the island is completely cut off from the mainland until morning.

At the stroke of midnight, Nana is found dead—exactly as she had predicted. Then, as the hours pass, family members begin dying one by one. Trapped on the island with no escape and no way to call for help, the surviving relatives are forced to confront decades of buried secrets, betrayals, resentments, and lies. As suspicion shifts from one person to another, Daisy races to uncover the killer before no one is left alive.

Filled with atmospheric tension, unreliable narration, family drama, and brilliantly executed twists, Daisy Darker is one of Alice Feeney's most acclaimed novels. Its haunting setting and shocking finale make it a standout modern mystery.
