A thousand years ago in an ancient Scottish landscape, a woman is on the run with her three companions --- a healer, a weaver and a seer. The men hunting her will kill her --- because she is the only one who stands between them and their violent ambition. She is no lady: she is the first queen of Scotland, married to a king called Macbeth. As the net closes in, what unfurls is a tale of passion, forced marriage, bloody massacre and the harsh realities of medieval Scotland. At the heart of it is one strong, charismatic woman, who survived loss and jeopardy to outwit the endless plotting of a string of ruthless and power-hungry men. Her struggle won her a country. But now it could cost her life.

It’s April 2020, and Edinburgh is in lockdown.

At the center of it, a novel: two crime novelists facing off over a chessboard. But it quickly emerges that their real-life competition is drawing blood. What unspools is a twisted game of betrayal and revenge, and as Karen and her team attempt to disentangle fact from fiction, it becomes clear that their investigation is more complicated than they ever imagined.

Their stories quickly get attention and create enemies for the two young up-and-comers. As they get closer to the bleeding edge of breaking news, Allie and Danny may find their lives on the line.
