Lily has spent her whole life not knowing the truth.
Now, one island will change everything.
When she was four years old, Lily's mother, Penny, walked out the family home and never returned. Growing up, Lily tried to block out the pain of betrayal. But years later, when Lily learns her mum's family used to own a holiday home on Osea Island, she can't resist booking a last-minute trip, hoping to finally find a connection to her mother.
But Osea is no ordinary place. Tidal and remote, it keeps its secrets close.
As Lily begins to peel back layers of the past, she uncovers a web of silence, betrayal, and pain stretching back twenty-five years. The island holds the truth of what really happened to Penny and why she never made it back home.
But some secrets aren't buried in the past. Nor are they still on the island. Some are closer than Lily ever imagined.
