It was summer, and Primrose woke knowing that it was going to be a very special day. The sun was already warm, and a light breeze stirred the leaves and branches of Brambly Hedge. It was a perfect day for a sailing adventure.Leaving the hedge behind, Dusty, Poppy, Primrose and Wilfred set off downstream in Dusty's boat the "Periwinkle," on a journey that will take them all the way down to the sea. But it isn't all plain sailing.
