Maggie

"I know truth is on Carlisle's side, I can't ignore that."

- Maggie's declaration to help the Cullens.

Maggie is a vampire member of the Irish Coven with the gift of knowing when she is lied to, and is firmly trusted by the rest of her coven.

Early life
Maggie was born in 1832 in Ireland. The Great Famine in the 1840s decimated her village, forcing her family to leave for America in search of a better life. Her family didn't have enough money for every member and Maggie was subsequently left behind to take care of her maternal grandparents, mainly because her parents did not love her as much as they loved her siblings due to her sensibility to lies. Siobhan and Liam found Maggie alone on the road to Cork, nearly dead from starvation. Maggie was able to recognize them as not being human almost immediately. She was changed shortly thereafter. Siobhan's mate, Liam, disagreed about changing her, but Siobhan persuaded him otherwise. Maggie enjoyed their company very much because they were routinely honest with each other and themselves.

Breaking Dawn
During Breaking Dawn, she arrived with the rest of her coven to see why Carlisle had contacted her. It was then she found out about Renesmee and because of her ability she was able to determine the baby was not an immortal child. She later stood as a witness for the Cullens to try and save the child. She, like the rest of her coven, returned to Ireland at the end of the book.

Physical appearance
She is described as small, short, thin and not physically imposing with bouncy red curls.

Personality
Maggie is very righteous and believes in justice. Whenever someone lies to her, she will loudly point it out even though it sometimes gets her into trouble. Due to this personality trait, she had difficulty dealing with authority, both on a parental and a community level, and was punished severely for it. This is why she felt comfortable with Siobhan and Liam because they are always honest both to her and to themselves.

Lie detection
In addition to her talents of a vampire, she is also gifted with the ability to sense whether someone is lying to her. This power manifested from her ability to read people's lies as a human. This becomes very useful when helping the Cullens, as when the Volturi came for Renesmee and Aro was about to tell her she was going to be fine, and Maggie knew that he was lying.

According to The Twilight Saga: The Official Illustrated Guide, she can read a person's appearance or actions to know if they are lying as well. She would feel physically uncomfortable with any kind of deception.

Film Portrayal
Maggie will be portrayed by actress Marlane Barnes in the second half of Breaking Dawn.
