This taut yet lyrical memoir tells of the author's experience with a baffling illness poised to take her sight, and gives a deeply felt meditation on vulnerability and on what it means to lose the faith you had and find something better. One day at the end of 2009, during a routine eye exam that Nora Gallagher nearly skipped, her doctor said, ';Darn.' Her right optic nerve was inflamed, the cause unknown, a condition that if left untreated would cause her to lose her sight. And so began her departure from ordinary life and her travels in what she calls Oz, the land of the sick. It looks like the world most of us inhabit, she tells us, except that ';the furniture is slightly rearranged': her friends can't help her, her trusted doctors don't know what's wrong, and what faith she has left just won't cover it. After a year of searching for a diagnosis and treatment, she arrives at the Mayo Clinic and finds a whole town built around Oz.In the course of her journey, Gallagher encounters inhuman doctors, the modern medical systemin which knowledge takes fifteen years to trickle downand the strange world that is the famous Mayo Clinic, complete with its grand piano. With unerring candor, and no sentimentality whatsoever, Gallagher describes the unexpected twists and turns of the path she took through a medical mystery and an unfathomably changing life. In doing so, she gives us a singular, luminous map of vulnerability and dark landscapes. ';It's the nature of things to be vulnerable,' Gallagher says. ';The disorder is imagining we are not.'
