O’Rourke boldly investigates the origin of her ills and possible cures. More crucially, she probes the cultural, psychological, and medical experiences of people with poorly understood or immune-mediated illnesses.

... a profound, sometimes lyrical, deeply moving portrayal of a vague constellation of illnesses.

The Invisible Kingdom is thus not a straightforward accountcharting the usual stages fromdisease onset to medical intervention to ultimate recovery—the hallmarks of many illness narratives.

At times, I wondered if [O'Rourke] ought to have assembled her story into such a clear, cohesive form; why not mimic the density and swirl of a decade spent in clueless flu-like miasma? O’Rourke is a devoted chronicler of each month spent in her corporeal purgatory, listing each new symptom and reliving every ache. I craved more mess, less linearity. But then again, who needs that? Sick people are befuddled enough and well people don’t need any more reasons to ignore them.

O’Rourke is not content with simply explaining what it’s like to be ill, though she does that very well. Instead, she deftly weaves scientific explanations of autoimmune illnesses and the broader problems of American medicine into a personal narrative of her search for answers.

Pensive.

O’Rourke examines her own experience with a lucid but compassionate lens, and she brings that same mix of analysis and compassion to the book’s reporting. It’s a delicate balancing act to write about a long journey of misery without being tedious or repetitive. She pulls it off by adding lyrical imagery and the words of other writers...to her descriptions of suffering, the peculiar treatments she found herself undergoing, and the effect her quest for healing had on her marriage. And yes, the book reaches a happy, though not uncomplicated, ending.

Personal and deeply moving.

With a poet’s sensibility, journalist’s rigor, and patient’s personal investment, O’Rourke sheds light on the physical and mental toll of having a mysterious chronic illness.

The author constructs that story from building blocks of personal narrative and science journalism, with deep dives into the technicalities of the immune system and the microbiome. The personal sections are engaging and well written.
