Eric Folder has moved to Oregon to attend Portland State University when an automobile accident leaves him stricken with migraine headaches. The resulting visual effects—something medical professionals term an aura—render him virtually blind and defenseless when a gang of street thugs attacks him. Desperate to see and needing to protect himself, Eric reflexively tears at the luminous lines of light and finds they have become tangible. When he pulls them aside, his present reality folds away with them, leaving him in better circumstances with his enemies vanished. Attempts to fold his way out of subsequent perils leave him in increasingly strange situations until, eventually, his world becomes a nightmare.
