Pien is in the bath. She likes to swim, just like her dog Boef in the ditch. But it does not work. The bath is much too small. And she doesn't know how to do it. 'Say, Pien?' Mom asks. 'Would you like to take swimming lessons?' 'Yay!' Pien shouts. 'That seems cool to me! Then I learn to swim. And I'll get my A!' The book is suitable for children aged 6 years and over.
