While hydrologist Adam Swan is engaged in humanitarian efforts in the Congo, he is kidnapped by rebel thugs and thrown into a makeshift prison. He is left to die—or worse—if his ransom is not paid. In a surprising series of events, Adam escapes the prison into an underground labyrinth where reality and sanity no longer rule. Tested by the gods of the underworld, Adam navigates the consequences of his past actions, which take him to the brink of death—and beyond.A fun, fast, thrilling ride by veteran author Elizabeth Engstrom, based on Matthew Lowes' Dungeon Solitaire: Labyrinth of Souls card game.
