This informative picture book immerses us in the fascinating world of bats. Together with Sophie, Karli, and their grandparents, we observe bats in the garden, go on a bat hike, and even build a house for these nocturnal flutterers. Informative double pages provide us with plenty of information about these small mammals: What do bats eat and how do they navigate? Who are their enemies and how can we protect bats? Realistic and atmospheric illustrations enhance the experience. This way, even parents and grandparents become true bat experts.
