Water - it covers 70% of the planet, and it's always on the move. In this charming children's book, Caren Trafford talks to Wasu, a very talkative water droplet, who reveals his view on life. Readers follow the water cycle, travel through the ages and discover things they never knew about water - why is it so important? Where does it go? What does it do in its spare time? Water droplet Wasu also reveals how he and other water droplets manage water so there is enough for future generations, teaching readers the vital importance of water conservation.
