Mi hermana, un zombi y yo (Monster Twins, 1)

Lupina and Umbrea are twins, but that's where the similarities end: one is a werewolf who failed her lycanthropy exam; the other, a prodigy witch who'd rather sing in a band than cast spells. When Umbrea messes up a spell and makes Cameron, the most popular boy in school, disappear, the sisters have to join forces with Parchi, a shy zombie, and Toronto, a human conspiracy theorist, to go looking for him in another dimension. Between uncontrolled fangs, magic that goes wrong at the worst possible moment, and a zombie puppet that drools a little too much, this group of friends will discover that growing up is scary... but it's much easier when you have monsters by your side.
