Bang. Bang. Bang. I jump as the knocks on the window crash above the roaring wind outside. Who could it be, at this late hour? I open the curtains and peer outside. 'Hello?' But the dark, the rain and the empty lane are all I see.

It's been eleven years since I last saw Jonah, after his brother died that stormy summer night. And now, without warning, he's back, living in his old house next door just like old times, on the remote Scottish island that is home. Where I used to imagine we'd stay, together, forever, sharing our lives and our secrets as we always had. But that was before.

Jonah's not the sweet boy I once knew. His mood is changeable, his behaviour unstable, our brief conversations are forced and awkward. And then the knocks on my window begin. It can only be him, but why, and what does he want? I used to love him. Now I don't even want to invite him in.

Because after all these years, I see our childhood secrets, the ones we swore never to reveal, in a newly terrifying light. Was his brother's death truly an accident? Could Jonah's secrets have been worth killing for? And how safe am I now, on this isolated island, with the man I used to love...?

A totally addictive and twisty psychological thriller with a jaw-dropping twist. Anyone who loves The Woman in the Window, The Wife Between Us and The Housemaid won't be able to put Childhood Sweetheart down!
