When acclaimed undercover journalist Casey Benedict is asked to interview a young woman with a life-limiting genetic condition, the patient's doctor alerts her to an alarming rise in antibiotic-resistant infections, tipping her off about a potential new wonder drug.

If the rumours are true, this new antibiotic could save millions of lives, but no one seems to know if the drug even exists.

Then tragedy unexpectedly strikes and Casey begins to suspect a cover-up. But she is not prepared to let the story drop, no matter how much danger she - or those she loves most of all - are put in.

A searing, page-turning, pulse-racing thriller that sees Casey on a hunt around the globe as she pursues a major exposé into pioneering medical research and drugs that could change the world.
