I tried to sell this little series to children, so I added some text to each drawing. The text (in Swedish) reads (roughly translated): Rufus and Serina are no ordinary children. Because they have fox blood in their veins! One night when the full moon shines Rufus wakes Serina. "Look, Serina, look! The sky's clear and it's full moon out!" he whispers as loudly as he dares. "Yes! We have to go out!" Serina whispers back to him.
