Respectable spinsters don't run off with their lovers to hunt down the secret to eternal life.

Unemployed, overqualified, and still scandalously unmarried, Ellie Mallory and her perpetually shirtless surveyor Adam Bates are at it again, chasing whispers of an ancient power through the elegant and treacherous world of late Joseon Dynasty Korea. But this time, they're facing a new sort of enemy-Adam's father, the ruthless American oligarch George Bates... and he's brought along the brother Adam thought he'd lost forever. Ethan Bates has bruises on his knuckles and a heart full of secrets. Plunged into a web of ghostly ciphers and imperial ambitions, he has no idea who he can trust. The brother he hasn't seen in seven years? Or the haughty (and unfairly handsome) Korean scholar who is very politely blackmailing him?

As the dead speak and loyalties divide, an unlikely alliance will lead Ellie and Adam to a race along the trail of clues left by Korea's greatest warrior, driving them from the intrigues of Seoul to a mountain haunted by the ghosts of their greatest regrets.

Because the power to overcome death isn't what it seems-and the man who shaped Adam's life is willing to pay a shocking price to claim it.

Return to the Raiders of the Arcana series with Mountain of Songs and prepare for an adventure thick with history, magic, and peril.
