She has paler skin than Susan but darker and healthier than Harry's, pasty from time spent in lab and mostly being outside at night.

Biography
Susan did not tell Harry of his daughter, and, deeming both parent's lifestyles too dangerous, found a new home for her. Her foster family were the Mendozas. At some point, Duchess Arianna Ortega of the Red Court found out about Maggie, and had her taken. Susan then chose to inform Harry to secure his help in her retrieval.

As of Ghost Story, she lives with the Carpenter family. (ref) Mouse is with her—Molly told Harry with a smile that "Chewbacca is with her." Uriel said that Temple Dogs can live for centuries. She could have him her whole life even if she becomes a wizard.

Changes
In Changes, Susan Rodriguez calls told Harry that their daughter that he never knew existed has been taken by the Red Court. Susan explained that she thought their daughter would be safer if no one knew. Harry is seething about his not being told. Susan tells Harry that Arianna Ortega has her. She and Martin are in town on a Fellowship assignment to find where Maggie is and what the Red Court plans are.

In seeking Maggie's whereabouts, Harry called up various spirits from the Nevernever using the summoning circle in his lab. One of the fire spirits showed Harry an image of Maggie for a few seconds. She looked pale, cold, grubby, and scared. She was reaching out for a flame possibly to warm herself by. Harry got no information about where she was, but at least he knew she was still alive.

Donar Vadderung told Harry he'll find his daughter in Chichén Itzá a few days where the Red King and Lords of Outer Night plan to use her as a sacrifice in Bloodline Curse. It turns out to be exactly what Harry needed for a successful recovery of Maggie. Donar further said that Chichén Itzá is the center of their power and that they could just wish him dead.

After Harry broke his back, he summoned Uriel who told Harry that he couldn't repair him or help him get Maggie. Uriel also told Harry that his daughter Maggie is still alive for now. In saying that he confirmed that Maggie is indeed his daughter, erasing the last little inkling of doubt. He said that Harry was her only hope and to consider Vadderung's words. Uriel ended by saying telling Harry to love his child, everything else flows from there.

His back still broken and out of options, Harry makes a deal with Mab to restore his body and give him the Power and strength he needs to save his daughter in exchange for becoming the Winter Knight.

Harry told to Ebenezar McCoy that Maggie is his daughter by Susan and that Arianna Ortega and the Red Court plan to use her in a ritual sacrifice for a Bloodline curse. Eben gave Harry his blessing to go rescue his daughter.

During the duel at Chichén Itzá, Arianna hinted that taking his daughter was never about him, and she was shocked that Harry didn't know what would be revealed about Ebenezar later that night.

Martin revealed that Arianna targeted Maggie because her "father is the son of Margaret LeFay who is the daughter of the man who killed her husband." It was her intent to get revenge on all of them. That means that Ebenezar McCoy is her great grandfather. Ebenezar is the Blackstaff and it was he who performed the hit on Casaverde that killed Paolo Ortega

After Susan sacrificed herself with Harry's help to kill all the vampires, Maggie is successfully rescued and sent to Father Forthill until she finds a new home. Harry decided it would be best if neither knew where the other was.

Ghost Story
As of Ghost Story, Maggie is living with Michael Carpenter and his family with Mouse. Uriel took Harry to see her and Mouse at the Carpenter home where it's surrounded by guardian angels. Uriel said that Father Forthill wanted to find the safest home to place Harry's daughter in.

Cold Days
In Cold Days, she's only mentioned as gone 'trick-or-treating', when Harry picks up Mouse, at the Carpenter's. (ref?)

Skin Game
In Skin Game, she asks Harry if he's mad at her, and when he answers he is not and asks why she would think that, she says because he's never around. She is considered a very lovable child, who at one point rides on Harry Carpenter's back while playing with the Carpenter children. By the end of the book, Harry has resolved to become more of a father to her in the future. (ref?)
