Athalie (Sacrificial Chronicles Book 1) by Jordan Elizabeth

Chosen as the yearly sacrifice, Athalie’s world crumbles into a devastating reality, but she knows her death will bring prosperity to her country and family. The emperor, however, has found a weapon created by the gods. During the full moon, he plans to activate it and eradicate their adversary, unaware it will actually destroy the planet.

Athalie, reborn and disguised, must hunt for talismans to neutralize the weapon’s power. Her journey will take her across the continent to countries unknown, to people she thought were her enemies, while being haunted by a magic she can’t fully control. The gods have allowed her one more shot at life, but if she dies this time, she won’t be reborn.
