“We are the minority the world does not accept,” Paige Mahoney tells us, referring to the struggles of clairvoyants, from soothsayers and mediums to her own high standing as a dreamwalker. In Shannon’s galvanic debut, the first in a series of seven novels, she brings us to Scion, a totalitarian state in England circa 2059, where “voyants” are designated “unnatural” and clairvoyance is outlawed. Torn from her beloved home in Ireland as a misfit girl, Paige, whose exceptional psychic powers are matched by nearly superhero physical prowess, found sanctuary in London’s criminal underworld, working for Jaxon Hall, a gang leader in the clairvoyant syndicate, until her arrest. Now she’s imprisoned in a penal colony, Sheol I, formerly the city of Oxford, a netherworld ruled by ectoplasmic beings called the Rephaim. Will Arcturus, Paige’s Rephaite keeper, prove to be as diabolical a tyrant as she fears? Not only has Shannon dynamically and shrewdly imagined every element of this spooky yet earthy world-at-war, from its unforgiving hierarchy to vile if essential herbal concoctions, encounters with monstrous predatory creatures, and the terror of “spirit combat,” she has also tapped into the timeless wellsprings of fear and prejudice, repression and resistance. The result is a dazzlingly brainy, witty, and bewitching tale of outrageous courage, heroic compassion, transcendent love, and the quest for freedom.
