No Man’s Daughter

An orphan girl marked for death. A would-be paladin thrown into war. And a mad prophet who would end the night forever.

...no more dusk...

Sadia and her chosen siblings are reviled in Qasira, scorned as al-Yetim - children of no one. But when she defies a zealot's attempt to burn a child alive, she becomes a fugitive, hunted for the life she saved. Her only chance of escape lies with a roguish dwarf and his ramshackle river barge. But fleeing is not enough. As she journeys farther from home, Sadia must fight against a horror she can't even comprehend - all to save a world that doesn't even want her.

...and no more dawn...

Gideon has long dreamed of swearing the Oath of Woe to become a paladin, but on the eve of his final trial, doubt gnaws at his faith. Before he can prove himself, war arrives at the monastery gates. Archoness Lorica, an infamous commander of the Church Militant, demands the untested recruits march to face a growing darkness - one responsible for the slaughter of her warriors. Thrust into an unfathomable nightmare, Gideon must survive his first battle... and learn that the price of glory is paid in blood.

...only the unsetting sun:

the burning Lidless Eye....
