The Salt Oracle

It's been seventeen years since the internet crashed and left the world broken... On the Bellwether, a huge floating college safe from the politics and war of the mainland, Auli looks after the Salt Oracle, a strange, uncanny girl who channels dangerous ghosts to sift information. When her mentor is found dead, Auli is promoted to his former position and investigates what she believes is murder - an investigation that causes her to question the people around her, the Oracle, and the changing nature of the ghosts that threaten them.
