What if marriage was the law? Dare you disobey? The Marriage Act is a dark, high-concept thriller from bestselling author of The One, John Marrs.

Britain. The near future. A right-wing government believes it has the answer to society's ills - the Sanctity of Marriage Act, which actively encourages marriage as the norm, punishing those who choose to remain single.

But four couples are about to discover just how impossible relationships can be when the government is supervising every aspect of our personal lives, monitoring every word, every minor disagreement - and will use every tool in its arsenal to ensure everyone will love, honour and obey...

Black Mirror meets thriller with a dash of Naomi Alderman's The Power.
