Lives entangle and agendas crash when Cassandra–newlywed, environmentalist, reincarnated prophetess–resorts to quantum magic to break a curse while secretly longing for something else: the power to stop global warming. Trapped between two lethal foes, one who murders to conceal a truth and the other to unearth one from our prehistoric roots, the activist must escape a labyrinth of her own creation and solve an impossible riddle, or she’ll pay with her life and all she loves for failing mankind in its final hour.
