Michaela Hertkorn, an instructor of politics who teaches in the Bachelor's Program and the Graduate Program in International Affairs, has published a children's book.

The Little Cloud Upset introduces preschoolers and young children to aspects of international relations and global affairs. Issues, such as human rights, the environment, refugee situations, war, and peace are discussed and illustrated in an age-appropriate way. The central character is a little cloud that travels, as a neutral observer, across the globe observing all sorts of global challenges. The cloud flies across melting ice caps in the polar region, watches children play in refugee camps, and remembers witnessing the fall of the Berlin Wall 20 years ago, an event that fundamentally changed the world and drew millions of people around the globe closer together. Though the book highlights problematic issues, it emphasizes the importance of cooperation and impact of individual actions.
