Three people. Three eras. One city. Endless possibilities. This is a novel of the distant past, the unimaginable future, and the search for the Holy Grail. Set in the city of London, the narrative is interlaced between three ages, in which a disparate group of heroes, criminals, runaways, and lunatics are drawn into the greatest quest of all time. And lurking behind it all is the entity known only as Omega.
