Ghost Exile book 6. Serious spoilers ahead for the earlier books.
It opens with them preparing to retrieve the Seal and the Staff -- Caina has already made plans to stow them elsewhere, and the danger of leaving them where they are is too great. And Sulaman asks Caina to come to the coffee house the night he is reciting. There, he tells her that if she goes, she will die.
She presses. If she doesn't go, the Apotheosis she knows Callatas is planning will happen, and kill many including her. So, she goes. Saying farewell to various people as she leaves.
An attack has them leaving at great speed.
And the rest of the tale involves undead baboons, winning a knife-throwing contest, a fear of plague, a magical object that doesn't work right, burning down a building, a dress, and more.
