The Last Starborn Seer

Leilani Stellarion is a princess of Arcelia and the last of the Starborn Seers. Her magic gives her prophetic visions, but it is volatile and slowly corrupts her mind, and her people shun her for it. Many also blame her for the Sickening, a wasting curse that has split the realms and pushed them into war.

Her own life is closing in as well. She faces a forced betrothal, and her mother's health is failing.

Then a prophecy names an ancient relic with the power to end the curse. Leilani resolves to retrieve it, and the route runs toward the Astral Mountain. She does not travel alone: envoys from rival realms go with her, so the quest depends on alliances with people who were enemies until now.

A romance develops along the way, and it is a fraught one. A vengeful spectre hunts her throughout, which keeps the pressure on the trip.

This is romantic fantasy, the first book of the Chronicles of Arcelia trilogy. Its central question is whether Leilani can reach the relic before her own power, or the spectre, finishes her.
