Author Daniel Kalla produces engrossing novels with an intensity that matches the challenge of his other role as an ER physician. His character-driven thrillers focus on themes that lie at the heart of his professional life and issues that are important to him, including such diverse topics as addiction, pandemics, superbugs, DNA evidence, and patient abuse. He has written global thrillers, historical suspense, epic stories, and psychological thrillers. In his latest novel, Fit To Die, Daniel tackles the issue of social media body shaming, body dysmorphia, and the sometimes-toxic diet and wellness industries.
