I read AVI - Banjer, shelter for Piers (AVI M4)

Do you dare to send an email on behalf of the mayor? Joris and Janne do, but will it end well? Super funny book on AVI M4 about two naughty children who stand up for lonely animals.

Who doesn't know it? You have a problem, but you need other people to solve it. Joris and Janne want to start an animal shelter and send an email on behalf of their father, the mayor, to have cages built. As long as their father doesn't find out about their plan...

Joris and Janne get everything done.
Well, that's what you'd think...
Because their father is the boss of the village.
But daddy doesn't cooperate.
So Joris and Janne come up with a plan themselves.
As long as daddy doesn't find out!
