Book excerpt: This is the second book of the series about Charlie, a young warthog living in the Kruger National Park, South Africa. It was a very hot day and Charlie was resting in the shade of a tree beside the river, thinking about his twin friends who lived far away in England. His brother Ben came along and invited him to play in the nearby waterhole. But, as he was wallowing in the mud and watching his brother having fun, he heard something moving in the nearby bushes. Charlie's exciting adventure was about to begin.Junior reader Ages 5-9
