From Blood and Ash by Jennifer L. Armentrout

remember. Serving the gods in the Temples was an honor, but this was still
a loss.
“Cease the tears,” the Duchess implored. “You know that this is right
and what the gods have requested.”
But this didn’t feel right. What harm would come in asking for one
child to remain at home with his parents? To grow, to live, and to become a
useful member of societyy? Neither the Duke nor the Duchess would bend
to grant such a simple favor. How could anyyone mortal be unmoved byy the
mother’s pleas, her cries, and her husband’s desolate hopelessness?
But I alreadyy knew the answer to that.
The Ascended were no longer mortal.
