Grimelda Hauchecorne is a very special witch. Unlike the other mice in Salem, she has a heart!

Everyone knows a heart keeps you from doing harm! Which means Grimelda can’t play evil tricks on people like the other witches.
So one night, she decides to leave Salem and slip out into the forest in search of someone who can help her get rid of her heart.
Along the way, she will meet the King of Nightmares, the Ghost from the River, and the Tree Man, but none of them can help her... until a friendly encounter will change Grimelda’s fate.
