The stakes have never been higher...

Detective Caelan Small is leading a quiet life, lying low and off the force until her old boss calls. A woman is in trouble, threatened with kidnap or worse.

Back in the Met, she goes undercover with a vicious drug dealer, entering a dark underworld of drugs, scammers and thieves.

As Caelan gets drawn in, she starts to uncover a shocking trade in human flesh. But information, the detectives' most priceless asset, is leaking. If Caelan isn't careful, she won't survive.

Searingly intense and utterly gripping, Time to Go is the perfect read for fans of Angela Marsons, Robert Bryndza and Line of Duty.
