ADVANCE PRAISE FOR A DANGEROUS DIAGNOSIS

“With its amazing feats of diagnosis and hair raising thrills, this gripping, masterful tale of healthcare run amok is exactly what the doctor ordered.”

—Sanjay Gupta, M.D. Associate Professor of Neurosurgery, The Emory Clinic; Chief Medical Correspondent, CNN

A Dangerous Diagnosis is a terrifically cinematic debut. With razor-sharp pacing, expertly planted twists, and characters you’ll root for, Shantanu Rai has written a novel you won’t be able to put down. I tore through these pages and loved every surprise along the way.”

—Caroline Leavitt, New York Times bestselling author of Pictures of You and Days of Wonder

“In A Dangerous Diagnosis, Dr. Rai cracks the code on how to thrill readers, while exposing them to the plight of doctors and patients. Diagnosis: riveting.”

—Dr. Samuel Shem, of The House Of God, and Our Hospital

A Dangerous Diagnosis exposes the fault lines of modern medicine: where profit trumps healing, doctors lose their calling and duty to care, and everyone else seeks to profit from the breakdown. Shantanu Rai’s story reminds us that sometimes it’s safer to tell the truth through fiction than to face it in real life. The most dangerous contagions aren’t viral. They’re human.”

—Dr. Céline Gounder, physician, epidemiologist, medical journalist, entrepreneur
