"A psychological thriller like no other. In Do No Harm, with a sharp and sympathetic eye, Daniel Ochalek reveals the complex workings of the minds of his two protagonists, Michael and Gabriel. How Ochalek intertwines their stories, how he plays with the reader's expectations, the twists he unveils, is masterful, surprising, and ultimately emotionally satisfying. Like the skilled surgeon he writes about, Ochalek delicately and skillfully peels away layers of story to illuminate his characters. Ochalek takes us into the world of mental illness with compassion and care. As we get to know them, the beautifully rendered protagonists upend our expectations. This is a thought-provoking, assured debut novel. Ochalek's prose is at once lean and poetic as we come to know our protagonists and the worlds they have fashioned for themselves, both internally and externally. A thoughtful page-turner, this book is a must-read for anyone whose life has been touched by mental illness." -Alfredo Botello, award-winning author of 180 Days "A harrowing, no-holds-barred exploration of modern medicine and what it does to one man's mind.
