"Tessa doesn't believe in magic. Or Fate. But there's something weird about the dusty unicorn tapestry she discovers in a box of old books. She finds the creature woven within it compelling and frightening.
After the tapestry comes into her possession, Tessa experiences dreams of the past and scenes from a brutal hunt that she herself participated in. When she accidentally pulls a thread from the tapestry, Tessa releases a terrible centuries old secret. She also meets William de Chaucy, an irresistible 16th-century nobleman. His fate is as inextricably tied to the tapestry as Tessa's own.
Together, they must correct the wrongs of the past. But then the Fates step in, making a tangled mess of Tessa's life. Now everyone she loves will be destroyed unless Tessa does their bidding and defeats a cruel and crafty ancient enemy."
I have no idea how to write a review for this without spoiling it. Just read it.
