Wind in the Ash Tree

``McMullen here continues the enchanting saga of life on a Welsh farm begun in her first book My Small Country Living ,'' remarked PW. It's a hard life, but the author, seeing the humorous side of every situation, writes with ``delicious wit'' about endearing creatures she loves and cares for, and various people, helpful or otherwise, who drift in and out of her life.
