Although the basic premise of this book is so far over the top that it unravels even total suspension of disbelief, it works, in its own very strange way. If you can accept that: A. any Government agency would do what this agency did, and get away with it, and B. That teaching newly blinded adults qualifies a sighted person to be able to function as a proficient blind person, then you can sit back and enjoy this book.
I was rather surprised to see that the author got a lot of things right, including white cane usage, navigation, and how a sighted person *should* guide a blind person (having been dragged, pushed, and once led by having the “kind helper” grab the tip of my cane and just start walking, expecting me to hold the handle and meekly follow), I rather appreciated. In addition, there is historical information that was new to me, and I found that rather delightful.
The story was feasible, just, and exciting enough to make this short book a very diverting read. I recommend it, with the provision that the reader not take it too seriously, and just enjoy it as a kind of fantasy/adventure.
