Connected

When Martha Carlin's husband is diagnosed with Parkinson's disease, she begins asking the questions conventional medicine could not answer.

Why this body? Why now? What had been building beneath the surface for years?

What follows is a deeply personal and intellectually ambitious journey through love, loss, scientific inquiry, and systems thinking. In CONNECTED, Carlin explores the hidden links between the microbiome, inflammation, environmental stressors, food, and the broader forces shaping chronic illness in modern life.

Part memoir, part scientific reckoning, and part challenge to medical dogma, this book traces one woman's search to understand not only Parkinson's but the larger chronic disease crisis affecting millions. Through the story of her husband John, her family, and her years of investigation, Carlin invites readers to see the body not as a collection of isolated problems, but as an interconnected system.

For readers drawn to root-cause thinking, health transformation, the microbiome, and personal stories with depth and conviction, CONNECTED offers a bold new lens on illness, healing, and what becomes possible when we stop reducing complex systems to simplistic answers.
