Mike May spent his life crashing through. Blinded at age three, he defied expectations by breaking world records in downhill speed skiing, joining the CIA, and becoming a successful inventor, entrepreneur, and family man.

It would allow him to drive, to read, to see his children’s faces. He began to contemplate an astonishing new world: Would music still sound the same? Would sex be different? Would he recognize himself in the mirror? Would his marriage survive? Would he still be Mike May?
