Karen's Witch - Baby-Sitters Little Sister Graphic Novel #1

Karen’s Witch is the first book in the Baby-Sitters Little Sister Graphic Novel series, adapted from Ann M. Martin’s classic novels and illustrated by Katy Farina.
Karen Brewer is absolutely sure that her next-door neighbor, Mrs. Porter, is a witch! With her black cat, strange potions, and mysterious meetings, Mrs. Porter—also known as Morbidda Destiny—seems way too suspicious to be a normal neighbor. So, Karen and her best friend, Hannie, decide to spy on her and uncover the truth.
But what if Karen’s imagination is running a little too wild? Will her curiosity land her in trouble? Or will she prove once and for all that a real witch lives next door?
