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?

Everything but the Truth is a cracker of a debut, all the more gripping because it could happen to any of us.

A fast-paced page turner with an emotional punch that sets it apart from so many other psychological thrillers (Mark Edwards, author of The Devil’s Work)

I have also written a book called Anything You Do Say.

It is out now on ebook and in January in paperback.

It’s the end of the night. You’re walking home on your own.

Then you hear the sound every woman dreads. Footsteps. Behind you. Coming fast.

You’re sure it’s him – the man from the bar who wouldn’t leave you alone.

You make a snap decision. You turn. You push. Your pursuer tumbles down the steps. He lies motionless, face-down on the floor.

Now What?

Call 999
Wait for the police to arrive. For judgement, for justice, whatever that may be. You just hope you husband, family and friends, everyone you love, will stand by you.

Run
Stay silent. You didn’t mean to do it. You were scared, you panicked. And no one saw. No one will ever know. If you leave now. If you keep quiet. Forever.

Which is it to be?

Here is what some people have said about it:

A Sliding Doors type thriller with a moral dilemma at its heart. Brilliant (Claire Douglas, Sunday Times bestselling author of The Sisters, Local Girl Missing and Last Seen Alive)

The novel is ingenious . . . a beautiful and original book (Claire Kendal bestselling author of The Book of You)

An expertly crafted novel full of drama and tension. . . An impossible feat accomplished with great skill. Bravo (Imran Mahmood author of You Don’t Know Me)

An addictive, exciting and devilishly clever book . . . exceptional (Holly Seddon author of Try Not To Breathe)

Next is No Further Questions.

The compulsive thriller from the Sunday Times bestselling author of Everything but the Truth and Anything You Do Say. You’d trust your sister with your life. But should you?

The police say she’s guilty.

She insists she’s innocent.

She’s your sister.

You loved her.

You trusted her.

But they say she killed the person you care about most.

Martha last saw her sister when she left her babysitting. Now, she’s watching Becky stand trial for murder. They are on opposite sides of the courtroom, hearing evidence that’s meant to finally bring the truth to light. What happened that night? And does Martha really want to know?
