The Book

An unfiltered look at the world inside MRI engineering.

Far more than a technical memoir, Through Fire is the personal account of a veteran engineer who spent decades installing and repairing MRI systems around the world — a career that put him at the forefront of an escalating corporate agenda bent on reshaping the rules and silencing those who spoke out.

It is a story about the people who keep these machines running, what happens when corporate culture starts prioritizing secrecy over safety, and the hard, quiet work of doing it right when nobody is watching.

What readers are saying

Early responses from engineers, healthcare professionals, and readers from beyond the industry.

★★★★★

A rare window into a world most patients never see. Shannon writes with the calm authority of someone who has spent his life keeping people safe.

Dr. Helen Marsh
Radiology Director
★★★★★

Equal parts memoir, technical primer, and conscience. I have never read anything like it. Required reading for anyone who works in medical imaging.

James Okafor
Senior MRI Engineer
★★★★★

You don’t need to be in the industry to be moved by this book. It is fundamentally a story about doing the right thing in a system designed to discourage it.
