Maeve

Maeve was a Faerie, and the Winter Lady. She first appears in Summer Knight.

Description
Maeve is Sarissa's twin sister and Mab's daughter. As the Winter Lady, Maeve was considered to be the Winter Queen in training—"The Queen who is to come"—to possibly become the future Queen of the Winter Court.

Maeve likes to play the part of the "Evil Kinkstress" (as Fix called it) and pulling everyone's strings. "She never passes the chance to tear the wings off a fly." Molly Carpenter, complains that Maeve was a 'really, really awful Winter Lady'.

In one moment, Maeve looked like she could be Lily's fraternal twin.

Maeve loves McAnally's lemonade.

Summer Knight
In Summer Knight, investigating Ronald Reuel's death, Harry Dresden meets Maeve in Undertown led by Elidee at Toot-Toot's request and met by Grimalkin, her servant. When Dresden asked her if she killed Ronald Reuel, the Summer Knight, she mischievously tries to force a deal on Dresden by inducing him with glamour to beget a child with Jenny Greenteeth that he would give to Meave. Dresden refuses. Lloyd Slate enters bringing a carved box which he hands to Maeve, kneeling. Maeve becomes enraged at Lloyd because the knife in the box—a military-type knife encrusted with black substance—was not what she wanted. She Kicked Slate, called him a stupid animal and threw the knife at him. He threatened to attack her with it. Maeve orders Jenny to subdue him which she does with a hypodermic needle.

Later, at the battle in the Valley of the Stone Table, Maeve charged up dressed in white armor with a dozen of her Winter Sidhe Warriors—whose armor had a snowflake design—in time to stop a score of Summer warriors from attacking Dresden and his team: the Alphas and the Changelings. She had her riders draw the Summer forces away so that Dresden could get to the Stone Table. Dresden left the traitor Lloyd Slate, who had been beaten badly by Fix with a big monkey-wrench, with Maeve. After the battle, Dresden awoke to the sight of Maeve and Mother Winter with Lloyd Slate manacled in ice in obvious pain.

"Something Borrowed"
In "Something Borrowed", displeased over the death of the Tigress, a favourite ghoul assassin of the Winter Court, and looking for revenge, Maeve sent her servant Jenny Greenteeth to ruin Georgia and Billy Borden's wedding.

Proven Guilty
In Proven Guilty, Lily called in Maeve to help answer Harry Dresden's questions about why the Sidhe are not retaliating against the Red Court for trespassing and summoning Outsiders on Sidhe lands. Dresden pressed Maeve on lawful grounds for what she did to Georgia and Billy Borden's wedding as they were under his protection when they killed the Tigress. Maeve conceded and told Dresden that Mab readied her force against the Summer Court and ordered that no action be taken against the Red Court. Maeve intimated that Mab has been overtaken by a "mortal contagion" has gone mad in a way similar to Aurora. Dresden left with the nagging feeling that it was too easy.

Cold Days
In Cold Days, Harry Dresden met Lily at the Botanical Gardens where she told him about a contagion that causes people or beings to do horrible things against their nature such as Harry Dresden's first three major cases. Maeve showed up and accused Mab of of being contaminated by the contagion and has gone "utterly mad" and plans to "unleash chaos on the world" that night—Halloween. Maeve and Lily say they think Mab's plan's had something to do with Demonreach. She said that Mab infected Lea during that time she had her bound in ice at Arctis Tor. Maeve and Lily ask Dresden to kill Mab, that as the Winter Knight, he can do it because his power comes from her.

Maeve is contaminated, allowing her to lie despite her nature. She is manipulating Lily into believing she can detect Nemesis and that Demonreach is a source of evil rather than a prison of it, but Dresden confronts her halfway through the ritual.

Maeve renders Dresden's team helpless, with the exception of Molly Carpenter hidden under a veil; Dresden finally understands that Maeve and Sarissa are twin sisters; Maeve chose Winter, but Sarissa did not choose any allegiance. When things got desperate, Dresden summoned Mab to deal with Maeve using the Circle of Power already set up by Maeve and Lily.

Maeve confronts Mab on her wish to kill her and her training of Sarissa to replace her. In spite, Maeve shoots Lily in the head, transferring her mantle to Sarissa. With no trustworthy host for her mantle nearby, Maeve believes Mab cannot risk killing her. Unbeknownst to her, also Molly Carpenter is a suitable vessel and is hiding nearby. Despite Dresden's pleas and best efforts, Karrin Murphy kills the Winter Lady, transferring also that Mantle.
