Abby

Abby is a member of Ordo Lebes, and, later, of the Chicago Alliance. She first appears in White Night.

Description
Abby seems to know what Harry Dresden and Karrin Murphy are going to say half a second before they say it. Harry thinks she may be prescient.

Abby seems to be a bit scatter-brained because of her prescient abilities. Harry explains that it's because she was trying to keep track of what was happening, what was likely to happen, and deciding what wasn't likely to happen, all in a few seconds—it's worse if she can see farther ahead, more possibilities exist.

Harry describes Abby as prettily plump, shorter than Murphy, probably in her mid-forties; with blond hair, and rosy, cherubic cheeks. She looked used to smiling.

White Night
In White Night, Abby is the first to open the door when Dresden and Murphy go to talk to the Ordo Lebes group. She as a small Yorkshire Terrier named, Toto.

Ghost Story
In Ghost Story, Harry Dresden sees Abby at a Chicago Alliance meeting where she gave a report on the status of various outposts of the Paranet. They lost contact with Oregon and fear the Fomor got them. Toto saw Dresden's ghost outside the window. Abby was inadvertently shot by Fitz's gang at Aristedes's order to warn off Murphy by shooting at her home.
