Karsten's mom comes home late from work one day, and she has a surprise … a kitten! Golden brown with a block spot around one eye – almost like a pirate! ‘What do you want to name him?’ his big sister Siri asks. ‘Maybe Buster?’ Mom recommends. ‘Or Messi?’ says Dad. ‘The world's best football player!’ ‘No,’ Karsten says. ‘I want him to be called … LEO! That's a good name for a lion, and I hope he'll become best friends with Lion Cub.’

In Karsten and Petra's Summer Book, we have combined two stories about Karsten and Petra. In Karsten and Petra Want to Learn How to Swim, Karsten and Petra are on a boat trip with Grandpa and his girlfriend, Esther, and they stop on an island. Neither Karsten nor Petra can swim, but they still have fun in the water, and after a while they even dare to dive down and put their heads completely underwater! So it seems that Karsten and Petra will most certainly learn how to swim soon. In Karsten and Petra Goes On A Trip, the two go on a family camping trip.
