The Spirit Box

Rachel's in trouble. She's a ticking bomb. A couple of co-workers bullied her into stealing a radical new drug from their employer, and now it's lodged inside her. They're watching her like hawks and her time's running out. John Bishop runs security for the company. As a father who once lost a teenaged daughter to an accidental overdose, his drive to hunt down the thieves and rescue their victim grows more intense with every lost minute.
He can never bring his own kid back. But he can save someone else's. Which is fine until the company realises that if the swallowed package bursts and Rachel dies, their secrets are kept safe and their problem goes away. Though Bishop's on the trail, he's an easy man to cut loose and discredit. But now he's Rachel's only hope. Either the package will burst, or the boys will cut her open to get it.
They're so convinced it will make them rich that they'll kill anyone who tries to take her, and hunt down anyone who succeeds. It can't end well. For somebody.
