Cuckoo

By: Callie Kazumi

Narrated by: Nathalie Buscombe

Brought to you by Penguin.
A gripping debut thriller with a killer twist at its core.

When Claire surprises her fiancé, Noah, at work for their anniversary, she’s the one who ends up being shocked to her core …

Because Noah left the company nine months ago, and she had no idea. How can she not have known?

Now he isn’t answering her calls. He won’t respond to her messages. He’s disappeared.

As Claire desperately tries to find her fiancé, her world begins to shatter as the truth about who Noah really is starts to emerge.

And things are about to spiral dangerously out of control . . .

‘Tense, deceptive and darkly compelling – a brilliant debut’ T.M Logan
