K for Kara 17 - Just a Joke!

Kara and her class play a new game on their iPads. It is funny and exciting to see everyone yell and curse, if something bad happens in the game. But it is just a joke. Or is it? Kara does not know, and it makes her feel weird.
This is the seventeenth book in the series about Kara and her friends. The books can be read separately.
