CODE: GREY

Dr. Cassie Yvonne Grey is a brilliant yet low-profile neurosurgeon whose extraordinary surgical skill has earned her the admiration of colleagues-and the resentment of enemies. Calm, methodical, and almost impossible to read, she has built a life where precision is everything.

When an anonymous invitation recruits her for a highly classified investigation into a growing number of unidentified bodies appearing across the country, Cassie accepts a commission that demands absolute secrecy. One mistake. One leak. One act of curiosity beyond her authorization... and the punishment is execution.

As the bodies pile up and the investigations grow darker, an unexpected encounter with the spirited cardiothoracic surgeon Clio Yvarielle Gallagher begins to unravel the carefully ordered life Cassie has spent years constructing. But the deeper she searches for the truth, the more every answer blurs the line between justice and evil, forcing her to question the people around her... and even herself.

Because sometimes, the greatest mystery isn't solving the case.

It's discovering whether the person you're trying to save... is yourself.

And when the line between good and evil disappears... how do you know you're still saving the right person?
