Lisa likes the juicy carrots, sweet strawberries and crunchy apples from Grandpa Siggi's garden. That's why she likes to be there herself at planting time. She is delighted when tender leaves sprout from the ground and bees buzz from flower to flower. Lisa is also very fond of honey. Siggi is a hobby beekeeper. "No bees, no apples!" he taught Lisa. Now he is taking part in the nationwide campaign "Every flower counts!" Committed farmers have created wildflower strips and flower meadows. This is where Siggi can send his useful fliers to the land of plenty for bees.Peter Jäger likes to pack the nature theme into lively stories with young pupils, who this time also learn a lot about the nearby moor with blue frogs, adders and wild geese in their school project.Because nature needs help, the clever guardian angels Piccolo and Donaldus are also there again. It's good to have someone take a look at things from a clearer height! The book awakens understanding and enthusiasm for nature and the environment and encourages people to get involved in endangered areas. All this without pointing the finger. Instead, it tells a story with family and school friends. It becomes clear that an understanding of nature is important for one's own life. Nature needs guardian angels, according to the subtitle, and so they are there, the invisible angels who give us heavenly insights. Reality mixes with the fairytale-like, sometimes very close together. After all, we are all our own guardian angels.
