Betty is back! The second children's book by Stefanie Kirschbaum features new stories about the highly sensitive and emotionally strong Betty and her friends. Grandma Trude and the pony Momo are, of course, back as well! Betty's keen sense of justice goes into alarm mode when she learns that her friend Philipp is being badly teased by other boys at school. And this happens just before their class trip! This causes her a lot of worry. But should Betty intervene, even though her school friend doesn't want her to? What can she do for fairness and solidarity? And how can she deal with her intense feelings and anger? Luckily, Betty can count on her friends, her clever Grandma Trude, and even the pony Momo! But what a shock: the class trip starts with a nasty surprise, and Betty can't just stand by and watch.
