Tony’s fiancee Felicity died of cancer, and even though she found a god who promised to cure her, the Irish trickster god of magic Gwydion, he insisted that she toss runes for it, and Felicity lost. (This is a modern world setting in which the miraculous powers of the gods are an accepted part of daily life.)
After the funeral, the Irish priests give Tony a letter from Felicity, who asks Tony to venture into the Underworld of Hades, who has claimed her because her parents worship the Olympian gods. Tony recruits Felicity’s best friend Marshall to take him on the road to the Underworld, and Marshall agrees to do it if he can film the trip using a psi-camera. But
When Tony finally gets his audience with the King of the Underworld, Felicity makes one more request of him that turns his life around. He won’t get back to the mortal world until this adventure is over, but at least he’s still with Felicity–even if she’s in disguise, hiding from Hades, and working for Gwydion on a secret mission to rescue the Irish faithful from the Greek underworld!
