«The Proteus Cure» by F.Paul Wilson, Tracy L.Carbone

In medical ethics, the line between right and wrong is often blurred. Who is to decide what is for the good of humanity?

Changing the world. One person at a time…

That is the mission statement of Tethys Hospital, run by Dr. Bill Gilchrist and his deformed sister, Abra. VG723, their revolutionary stem-cell-based therapy, appears to be capable of doing just that for the cancer patients who come to Tethys. VG723 is often their last hope. But if they match the protocol, they're virtually guaranteed a cure.

Dr. Sheila Takamura, a young, dedicated oncologist, is proud to be involved in the clinical trials. Once the FDA approves it for widespread use, VG723 will revolutionize cancer therapy. That is why she's alarmed when former patients return with bizarre syndromes. Yes, they're cancer free, but they're experiencing dramatic changes in their hair and skin and general appearance. When she investigates a possible link to the protocol, those patients start dying. As the body count grows, Sheila finds her own life in danger. She comes to suspect there might be a literal meaning behind the Tethys motto – but can she learn the truth in time to save herself and millions of others?
