Adrian Rogers cleverly blends a tale of love and of the quest for the Grail which stretches over time and centuries and geographic locations as varied as the journey itself and all that it represents. John Finniss is just an Anglo-Irish schoolteacher in Darwin, who has reached breaking point in his career due to mid-life crisis... or is he? Why has he started recalling childhood dreams of life as a druidic bard of Irish origin, at the court of King Arthur in 6th century Britain? Is it simply memories of a past incarnation, or is he really two people, able to exist in both past and present simultaneously? And why does the Time Tunnel begin to materialise, as if to draw him back?
He decides to find the answer over the course of a weekend, by accepting the challenge of the Time Tunnel, letting it take him back to his boyhood in Celtic Ireland, then to Britain in the Dark Ages, and knowing that only thus can his crisis be resolved John Finniss lets his dreams become reality. He becomes a friend and confidant of King Arthur, participating in all the great events of his reign, and in doing so meeting the love of his life, Elen, a princess of North Wales. But nothing runs smoothly, and the wars of that time - in which he has a part divide them. So - as a druidic initiate under the guidance of Merlin he takes refuge in the Grail Quest, and an otherworld ritual that brings it close to realization.
Yet all the while events in his worlds (past and present) are being manipulated by the Annunaki gods, seemingly for their own ends, until it seems impossible that Finn and Elen will ever re-discover one another. Nonetheless, as Finn lies wounded after the last battle -- when Arthur has been taken away to Avalon, Elen finds him at the end of a day's fighting, as the Time Tunnel materializes for the last time over the battlefield... but can they reach it, and return to the modern world before he dies of his wounds? And even if they do manage to enter, can they survive its terrors in the state of no-time as they journey through?
