The Speed of Dark

I adored this book until the last...40 pages or so. The ending made me want to scream and throw things. Why cure him of his autism and take away everything that made Lou him? As an autistic person, the treatment of this as a good thing (because look, now he can be an astronaut! It only requires he give up everything pleasurable and good in his life, and all his relationships!) Ugh. Still 4 stars, because of just how much I loved everything preceding, but just...ugh.
