Grips from the first page. An emotive thriller which I couldn''t put down.'' Carys Jones, author of We Are All Liars

What would you hide to get everything you ever wanted?

After years of infertility and heartbreak, Hannah and Charlie are finally going to get their dream family. Two-year-old Isabelle is a week away from being theirs; they just have to get through the final adoption approval process.

But when a global popstar is found murdered at the celebrity members’ club in their sleepy Oxfordshire village, Hannah fears her past is finally catching up with her. Exposing the truth could see her lose everything… her husband, Isabelle – perhaps even her life.

But Hannah doesn’t realise that Charlie has his own secrets, and, in trying to save her, has put them more at risk than she ever thought possible. As the couple get drawn in further to the murky world of celebrity and murder, they soon find themselves caught in a nightmare, forced to make terrible choices.

How many bad things will a good person do to hold onto what they love?
