Comments:
A good story about a telepathic man whose consciousness has become unstuck in time so that he does not experience things in order. His quest is to cure the disorienting condition. As befits the subject, the story is told in a very fragmented manner. The setting is pretty far future, with thousands of planets colonized and FTL canals connecting them.
