Little Missy Muffet comes from a peticular family: human from a mother, spider from a father, she knows her nursery rhyme by heart, and arrives at Monster High slowly, carried by the spidery strangeness of her childhood. But the relationship between Humanity and Monstrosity is the most painful philosophy of this century, and quickly, Missy becomes a glass bridge between lions and chimeras, clumsily accessorizing with a foreign behavior that the most inclined creatures view with suspicion. Indeed, a month ago, the World of Monsters suffered a great erosion: Dracula disappeared at sea, and it is up to his only weakened heir, Draculaura, to take control of a vital part of its ruins. Alas, this is only the beginning of a series of 'coincidences' which will include a potential new war with the Van Hellscream, especially with the return of their patriarch, who seems determined to take a steely revenge on Monster High... And on the entire Muffet lineage, following bad ancestral associations, which created a very sinister melody stuck in the middle of times.
