Peter Carnavas' Little Treasures aim to uplift and inspire children and parents through exploring love, the environment, family and the importance of self worth. In Last Tree in the City, Edward stumbles upon a beautiful tree. It is the last tree in the dull and colourless city. Then one day the tree is chopped down and all that is left behind is a branch. Edward, in attempting to revive the tree, causes the whole city to follow his lead as they realise the importance and beauty of nature.
