Cole, what's wrong?
Former detective Gavin DeGrassi likes his new life and his job as a university professor, molding the minds of the next generation of law enforcement. It keeps him in the field he loves, but out of the media and out of the danger he seems to draw. He's settled and happy with his partner and Dom, Ben Haverson.
It's Myah.
Until a middle of the night phone call from his brother, Cole, whose desperation and fear yank him back into the world of criminals and countdowns. Only this time, the stakes are much higher.
She's missing.
Detective Myah Hayes, Gavin's sister-in-law and former partner, has a past of her own, one that has returned to claim her. With only their instincts and the help of a rogue CSI, Gavin, Ben, and Cole will do whatever it takes to find Myah, following a flimsy trail of evidence to Chicago, where all is not what it seems-dirty cops, moral pimps, and a nest of snakes who call themselves businessmen.
They're on a collision course with the worst of humanity, and more than Myah's life is caught in the vortex. Can they find her, and if they do, will there be anything left to save?
