Speak of the Devil

A Witchy Graphic Novel

By Sweeney Boo

On Sale: 3/3/2026

In the thrilling, witchy sequel to Over My Dead Body, Abigail fights to clear her name as strange occurrences continue to plague Younwity Hidden Institute of Witchcraft—a spooky teen graphic novel perfect for fans of Wednesday Addams and The Chilling Adventures of Sabrina!

Months after Abigail and her friends thwarted a dark magic ritual that threatened to destroy Younwity Hidden Institute of Witchcraft, new dangers and long-buried secrets bubble to the surface.

As autumn turns to winter, a mysterious rune-dotted fissure has appeared in the school grounds, and no one from the Coven is able to seal it—no matter how powerful their magic is. Even worse, it’s believed this fissure is the source of hazardous tremors that continue to rip through the grounds, threatening the institute’s very foundation. Abigail is certain this is all her fault and hatches a plan to seal the fissure herself, but when her ritual goes sideways, she awakens a long-dormant entity hellbent on revenge. To put things right, Abigail will need to unearth the true history of Younwity Institute and, just maybe, unravel the secrets of her own forgotten past along the way.
