Eternal Thorns by Ken Sanchez

In a Forest of Thorns Love is Both Poison and Cure…

When Silas Ashworth is exiled to the mysterious Thornhaven Manor for exposing his noble family’s corruption, he expects a cold, empty estate on the edge of the forbidden Eldergrove. What he finds instead is a house alive with ancient magic and a forest guarded by Thorne – a powerful spirit whose ethereal beauty is matched only by his bitter hatred of the Ashworth name.
As Silas uncovers the truth about his ancestor’s devastating betrayal of the forest realm, he finds himself drawn to the vengeful guardian in ways that could either heal centuries of division or destroy both their worlds. But darker forces are stirring. Every moment Silas and Thorne spend falling in love gives strength to an ancient shadow entity that feeds on their connection – one that could corrupt everything they’re fighting to protect.
With time running out and corruption spreading through the forest, Silas must make an impossible choice: walk away from the one he loves to keep him safe, or risk everything to prove that some loves are worth fighting for – even if they might cost you everything.
