Detailed and accurate illustrations of plants and animals around a 300-year-old oak tree will delight and educate young readers in this lovely seasonal story. Anna and Benjamin live in the city but love to stay with their cousin Robin in the countryside. Robin takes the children to see his favourite tree in the nearby forest: a 300-year-old giant oak. Each time the children visit, they are amazed at how the forest and the mighty oak changes with the seasons. In autumn, they build a cosy den in the tree's roots to watch the squirrels. In winter, they learn to ski in the shelter of the forest. In spring, they search the forest for animals. A blend of fiction and fact to delight and inform.
