They shared a terrible marriage, now they share a murder

Mia and Rami's marriage is dead. They're in their thirties and reeling from a miscarriage, but love left long ago. Rami, a fantasist, believes they can revive it, but Mia has reached her limit.

On a rainy drive, she finally asks for a divorce, but in the ensuing argument their crumbling world collides with another: a motorcyclist. Desperate to avoid punishment, they're forced into a toxic alliance.

Will this shared crime resurrect their marriage, or be the final, fatal blow?

Until Death Do Us Part is a domestic thriller about a failing marriage, an accidental killing, and the toxicity of secrets.

What people have said:

“A wickedly dark, compulsive and gripping thriller pulsing with secrets. loved it.” Gytha Lodge. Sunday Times bestselling author of She Lies in Wait.

“I’ve Read Worse.” Adam Croft. International bestselling author of Knight and Culverhouse, Her Last Tomorrow, and The Rutland crime series.

“I went into Until Death Do Us Part fully expecting a typical domestic thriller—one with no real surprises and characters so irritating you’re just waiting for it to be over. I’m happy to say Mark’s book is nothing like that.
This story is edgy from the start. The dynamic between Rami and Mia is messy, trite, and emotionally cold. At first, Rami comes across as weak and passive—but that perception doesn’t last long. And Mia? She’s a piece of work. These two shouldn’t even be married, which only adds to the tension and dysfunction simmering beneath the surface.
Then, during a drive in dangerous, inclement weather, everything changes. What follows forces both Rami and Mia to resort to actions and decisions neither of them ever believed they were capable of. From that point on, the suspense tightens and refuses to let go.
The plot is solid, the tension is relentless, and while the characters aren’t likable, they’re compelling—and that’s what makes this story work so well. Add in a truly satisfying ending, and you’ve got a domestic thriller that delivers on every level.
Highly recommended.” - BookSirens reviewer
