Then Justin and Mae are assigned to a diplomatic delegation headed by Lucian Darling, Justin's old friend and rival, to go into Arcadia, the RUNA's dangers neighboring country.  here, in a society where women are commodities and religion is intertwined with government, Justin discovers powerful forces at work, even as he struggles to come to terms with is own reluctantly acquired deity.
Meanwhile, Mae - grudgingly posing as Justin's concubine - has a secret mission of her own: find the illegitimate niece her family smuggled away years ago.  But with Justin and Mae resisting the resurgence of the gods in Arcadia, a reporter's connection with someone close to Justin threatens to expose their mission - and with it the divine forces the government is determined to keep secret.
