The Immortal Crown

Penguin presents the unabridged, downloadable, audiobook edition of The Immortal Crown by Richelle Mead, read by Emily Shaffer.
When Justin March and super-soldier Mae Koskinen are assigned to a diplomatic delegation going into Arcadia - a dangerous neighbouring country to the RUNA, in which religion is intertwined with government - they discover powerful forces at work.
Mae also has her own secret mission: finding 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 back home threatens to expose their mission - and with it the divine forces the government is determined to keep secret.
