Frog lives by the river, under his leaf. Life was just perfect for him and his neighbours, the Ducks and their ducklings, and the Water Voles and their baby water voles. Then one day a beaver appeared, looking for a new home. Frog tells him that the river is a lovely place to live, so beaver decides to stay and tells the residents that he is going to build the biggest and best dam that they will have ever seen. As beavers dam gets bigger, the river starts to dry up as his dam is blocking the water from getting through. Frog tries to explain to him that his actions are causing the others problems, but beaver doesn’t listen. In the end the families have to move to the other side of the dam. But when the dam breaks, the residents are left homeless again. It’s up to a very sorry beaver to help them build their homes once again. I love this sweet, yet educational book. It teaches children that sometimes what people (or animals) do can have consequences, and that we should all be more caring about each other, and not just think about ourselves. The illustrations are bright and colourful. They bring joy to the story, and show exactly what is happening throughout. A lovely, feel good book, that will children will enjoy reading over and over again.
