University Press books are often lumped into categories like: academic, obscure, expensive. And that certainly can be the case but is by no means an accurate assessment of most books printed by Univ. presses. Mara Faulkner, OSB, has written a fine book that is part memoir of her father's blindness, a look at retinitis pigmentosa(which she, too, has) and a larger meditation on blindness in the many forms it can take.
Here is the publisher's page. I'm also going to link to an interview she's done with Luke Mancuso where they discuss not only her book but a new course she's teaching entitled The Past, Present and Future of the Book. Scroll to the bottom of the page for the audio. It is an hour long piece and I found it to be enlightening--a discussion with two people who greatly love books but also aren't willing to stick their heads in the sand.
"Going Blind" discusses a great list of other books that deal with blindness. More than anything else I could say, I should simply state that it is a book filled with grace in both its language and its treatment of the people within. It should not be limited to an academic or niche audience. It has loads of potential as a general interest book and for book groups. It is memoir without the fireworks or madness nearly required by its categorization. It's just good.
Up-front: The book I'm discussing is by a former college professor of mine. She was a marvelous teacher and mentor. But the truth is that I know a lot of people with books and I don't go around pimping just anything.
