Book 4: Hilja and the operation Christmas magic
Christmas is coming to the Green house! There’s only a month to find out:
a) whether elves really exist, b) where did the gifts disappeared from the hallway, and c) whether things you can’t see can still be true.
Hilja’s sister Veini claims that Christmas is just a publicity trick, but Hilja decides to prove that Christmas is real and magical. A secret operation begins, and it involves making an elf trap, lots of secret notes and spying on neighbors. Even Santa is not having it easy – he has to take part to Hilja’s lie detection test.
Many, many miscommunications are ahead before the family of the Green house can finally calm down for Christmas.
