Her Last Scream

Across the US, a secret network of crisis centres has been devised to permanently relocate women in danger from abusive spouses, stalkers, even murderers. Women enter the system and pass through temporary safehouses to reappear a thousand miles away, with a change of identity and a new life free of fear.
Detective Carson Ryder and his partner Harry Nautilus have their work cut out in gaining the trust of the women who run the scheme after a woman's body appears in Mobile, Alabama. A second similar death suggests someone has broken into the system somehow and pulled the women from it, before leaving them to die in misery.
To discover where security has been compromised will be near impossible: the system has been designed so that each cell is sealed off from all others, remaining anonymous and fiercely protected. The only option is for an undercover policewoman to enter the system posing as a threatened woman, making herself a target. There's only one candidate: fresh out of Mobile Police Academy, smart, beautiful, good at acting and the perfect age. She's also Harry's niece - Reinetta Early.
He tried to keep her from joining the force but Reinetta idolized Harry from childhood, always intending to follow in his footsteps. Harry Nautilus has spent years convincing his older sister that he would keep an eye on Reinetta and keep her safe from harm. Suddenly he's unsure if he can even keep her alive...
