The protagonist — Reagan Moon, reporter for a publication specializing in the paranormal — is the guardian of a Tau (a cross-like shape based on the Greek letter) left in his care by his girlfriend, Ellie, before she was lost in an explosion. Why is it important?
Why does a famous recluse want Reagan’s help, and why are psychics and mediums being killed?
Framed for the murders and sought by those who want the Tau, Reagan seeks help from Matisse, a former Jesuit priest who is now the keeper of an archive of paranormal arcana. Matisse’s mysterious daughter, Kanya, and a cheeky guardian angel, Bernard, become Reagan’s sidekicks on a mission to take down the forces of evil invading this world and to solve the mystery of his girlfriend’s death.
Along the way, there’s humor, a bit of angst and self-reflection, action, and the introduction of strange goggles that enable Reagan to see into another dimension. (In my mind, they’re clunky steampunk cool.)
But whatever mix of genres or monsters it might be, it’s definitely recommended reading.
