Riding the unicorn

John Willoughby is being pulled between worlds. Or he is going mad, 'riding the unicorn' as his prison officer colleagues would say. It's clear to Willoughby it must be the latter. Disappearing in the middle of his prison shift from among convicts, appearing in a makeshift medieval encampment for minutes before tumbling back to the real world, Willoughby believes his mind is simply breaking apart. But Willoughby finds that in another world, with a second chance he may be the kind of man he had always wanted to be after all.
