Who Is Sorcha In A Daughter Of The Forest

In Juliet Marillier's "Daughter of the Forest", Sorcha, the protagonist, is the seventh daughter of six sons: Liam, Diarmid, Cormack, Conor, and Padriac. Life in Sevenwaters is perfect until her father interacts with someone who eventually puts a spell on all her brothers. To make her life the way it was again, Sorcha must leave her home and go on a journey of love, loss, magic, and legend. On this journey, she will have to choose between the land she has always lived in and her love with another.
The path to this journey begins at a party when a Briton, the enemy of Sorcha's people, is caught and imprisoned in the household. Finbar - one of her brothers - wants to help the Briton escape. They succeed in this task, and Sorcha now travels to the house of Father Brien - a recluse who lived south
Sorcha eventually has to leave the Briton, for surprising news has come - her father, who had been hurt from the death of his wife for so long, was now getting married to Lady Oonagh. During the first few days of their engagement, Lady Oonagh causes mischief in the house; she puts poison in a woman's food, uses her magic to make Cormack beat his dog, and uses her magic to kill Padriac's animals. A while after this, the siblings gather around the remnants of their tree that Lady Oonagh managed to destroy. The plan was for Conor to call the Lady of the Forest for help. However, as Conor calls the Lady of the Forest, Lady Oonagh's spirit appears instead. She turns the six boys into swans and Sorcha manages to escape. As Sorcha reaches the deeper end of the forest, the Lady of the Forest tells her the task she must complete - she must sew
