Time is the Simplest Thing, by Clifford D. Simak

I've read this one before, because I vividly remember that the Pinkness made Shepherd Blaine's mind reflective and shiny. That was meant to protect him, but in reality marked him as a big shiny target for anybody with mental powers.

The book is dull and meandering. The characters' motivations rarely made sense, and the ending was not satisfactory.
