The Seer: Legends of Pern Coen. Fated, #3

Fianna's power has almost reached its peak.  And its servants are coming for Seren's throne.  Seren had no choice but to label Bran a traitor, but with his unexpected return, she will have to discern if she can truly trust the man she loves while also fulfilling her vow to protect her people. But Bran isn't the only threat she faces from within her own court. As Fianna's power grows, secrets of the past refuse to stay buried.
Seren is not the only bloodkin of Cadfael who has a claim on Blaidd's throne and whispers abound of a man who is able to save Blaidd's people from Fianna's destruction with his immense power. Seren will have to be willing to sacrifice everything to drive Fianna out once and for all, for if she doesn't, the Clan of Blaidd will become nothing but ash and rubble.  Dive into a new epic romantic fantasy series with shapeshifters, mythical monsters, and ancient magic set in a Celtic inspired world.
This trilogy features elaborate worldbuilding, a fierce seer heroine, a wolf shifter hero, dark magic, forbidden love, fire monsters, political intrigue, and a low spice romance.
