The Knight and the Moth by Rachel Gillig — book slip

Sybil Delling has spent nine years dreaming of having no dreams at all. As a Diviner in the great cathedral, she receives visions from six unearthly figures known as Omens, allowing her to predict terrible events before they happen.

As she nears the end of her service, a mysterious and heretical knight named Rodrick arrives, challenging her beliefs and visions. When her fellow Diviners begin to vanish, Sybil must seek Rodrick's help to uncover the truth.

Together, they must navigate a world filled with peril and gods, where only a heretic can defeat a god.
