Grace

A woman. Kit had an impression of gray eyes, sun-damaged skin, and close-cropped brown hair. She wore a bulky assortment of leather garments, her jacket and long tunic stitched together with twine in a way that looked primitive, like she’d made them herself. Her legs were bare and battered, covered with bruises and scratches.

In Preppies of the Apocalypse, Grace is a human who lives in the ruined future land. As a baby, changelings stole her away and left a changeling baby--who would grow up to be Ivy Garrett--with the Garrett family. She is fiercely loyal to Kit Garrett. Because of her changeling connection to Ivy, Grace shares some of Ivy's supernatural abilities--namely her ability to cross through multiple timelines.
