Lily Potter is an average 15 year old living in the United States in 2011. When magic upheaves her life and drops her and her younger brother into a beloved world she thought was fictional, she discovers old family secrets-and family in general.

Long before she was sorted into the Gryffindor house, Kefira Walsh was known as the "little lion" in her family. The youngest of the four Walsh girls, Kefira wasn't supposed to survive long after birth, but as she celebrates her eleventh birthday, the girl has already proven that she is a warrior. With her fearless attitude and a wild mane to match, Kefira prepares to attend Hogwarts School of Witchcraft and Wizardry as the only witch of her family. Aboard the Hogwarts Express, she meets a boy by the name of Neville Longbottom. Neville initially comes across as a nervous boy, who stutters and stammers when he talks and won't look a person in the eye. But Kefira takes a liking to him instantly as she can see the lion in the boy's heart waiting to be woken. All he has to do is learn to be brave.
