I have written a book called Everything But The Truth. It was released in March 2017 and became a Sunday Times Top 10 Bestseller.

Just how much can you trust the person you love?

Everything but the Truth is Gillian McAllister’s stunning breakthrough thriller about deceit, betrayal and one woman’s compulsive need to uncover the truth

It all started with the email.

Rachel didn’t even mean to look. She loves Jack and she’s pregnant with their child. She trusts him.

But now she’s seen it, she can’t undo that moment. Or the chain of events it has set in motion.

Why has Jack been lying about his past? Just what exactly is he hiding? And doesn’t Rachel have a right to know the truth at any cost?
