"Think 'medical thriller' and Robin Cook usually comes to mind. This should be replaced by Mark Anthony Powers, because the arrival of another addition to the Phineas Mann series lends added value to the genre. Readers seeking a vividly realistic medical thriller will find this especially thought-provoking."

- Diane Donovan, Midwest Book Review

"A stirring capstone to a thoroughly enjoyable four-part series that I encourage all to read. Mark Anthony Powers uses his characters and story line to highlight the continued importance of high-quality clinical medicine. I strongly connected with Phineas as he strives to remain relevant to his colleagues, patients, and his wife, Iris."

- Carol Hamilton, M.D., author of Hitchhiking to Madness: A Memoir

"A masterful reminder of the danger of bias in the workplace and in life. Mark Anthony Powers weaves his professional experience of circumstances surrounding illness and how it affects the whole family, ending in an unexpected catharsis."

- Ruben D. Gonzales, author of the Black Mountain Mystery series

"Nobody writes medical mystery like Mark Anthony Powers. This medical thriller combines a desperate race to solve a diagnostic dilemma while Phineas confronts his own mortality. A compelling page turner that is genuinely surprising and full of heart and humanity."

- Christopher Ethan Cox, Professor of Medicine, Duke University

"Mark Anthony Powers' latest novel is an insider's look at physician Phineas Mann's struggles with becoming invisible in his field as he and his wife age and face inevitable illnesses. In a thoughtful tour de force that takes us behind the scenes in hospital rooms and clinics, Powers explores the power of family, the bonds created in a long-term marriage, the ways pets communicate with their owners, and the resilience of the human mind, as he draws on Dr. Mann's bravery when facing a drama that can determine his life, death, and magnificent career. The Desperate Trials of Phineas Mann teaches, inspires, and pulls on the heartstrings."

- Dawn Elaine Von Wald, President, Rewired Creatives, Inc.

- Eleonora Piazza, Editor-in-Chief, Not for Vanity

"Mark Anthony Powers gives us an authoritative glimpse of the human travail that accompanies the evolution of medicine, while encouraging readers to grapple with diagnoses, the shortcomings of doctors and medical institutions, and the value of persistence and vision to the world of medicine. An instructive and enjoyable read!"
