Homeless and jobless following the death of his adoptive parents, Sebastian enrols at a college of natural medicine which boasts a sanctuary modelled on an ancient Greek healing centre. After a night in the temple, he dreams of Apollos, a young Athenian defeated in a pankration contest, suffering memory loss. More dreams follow, decrypted by Sybil, the lecturer who insists he keeps a dream journal. Seb is kept busy in the 21st century by a budding relationship with Fliss, which stalls when she tries to persuade him to search for his birth parents. Meanwhile, Apollos, in the fifth century BC, readies himself to attend the festival of the Greater Eleusinian Mysteries, to discover the secrets of how to avoid the perils of the underworld and make it to Elysium.
