For reading aloud and by oneself: Finally, vacation with the parents at the seaside cottage. But somehow, from the very beginning, things are off this time. Linn's mom and dad are arguing because dad has to go back to the city, and as a result, mom is really angry. That’s already enough to ruin anyone's holiday mood. But as if that wasn't enough trouble, even at just nine years old, Linn's favorite vacation friend Smilla has brought along a strange girl to the beach. What’s going on? Why does no one notice how lonely Linn feels? Why does no one want to know how she is doing? Maybe sometimes it takes lightning, thunder, and hail to clear the air and help people see each other better.
