Desperate to rid her husband of the burden of caring for her scleroderma and end-stage kidney failure, Betsy Daniels seeks out help to end her life. But her friend, a cancer survivor, convinces Betsy instead to pray like she’s never prayed before. Several weeks later, the gambit seems to have paid off. Her kidney failure has resolved and even her family doctor, Regina Thomas, can’t find a reason why. Her body is miraculously healing, the scleroderma vanishing as if it never existed. Betsy is convinced she’s been blessed with a miracle and wants the world to know the word of God.

But Regina isn’t convinced they’re witnessing God’s work. She’s a woman of science, and she fears Betsy’s spontaneous remission may have other consequences. Betsy is changing, both outwardly and inwardly. And Regina is suffering from her own medical problems, and if she can find out why Betsy is healing, perhaps she can help herself as well.

What Betsy and Regina don’t know is that a hired killer is also seeking that answer. He’s already murdered a biotech researcher who claimed to have developed a panacea for all disease, but the prototype itself is missing and all the supporting research destroyed. Having tortured and eliminated the researcher’s friends and coworkers, the killer has tracked the prototype to Clearwater, Florida, where Betsy and Regina live. And he will stop at nothing to get it.

He’s not the only one. Before his murder, the researcher reached out to his friend, Swiss Professor Friedrich Gersch, a genius who has tackled some of the biggest biotechnological threats to society, and gave him clues to finding the prototype. Gersch has also traced those clues to Clearwater, and is determined to find the prototype before it falls into the hands of his greatest enemies.

Whoever finds Betsy first will hold the key to the greatest medical discovery in human history—or its greatest threat.
