If you believe that travel writers should inform rather than editorialize, nip out and buy a guidebook. But if you value an intensely personal account of travel as a window into both a physical and psychic landscape, then Frances Mayes is just the ticket. The author of four books on Tuscany (including the smash hit Under the Tuscan Sun) compresses five years&rsquo worth of travel into a single year, arranged by season. The sights, sounds, smells and above all, taste, of the Mediterranean and the British Isles pass through her alchemical powers of observation to create a unique take on these well-known parts of the world.
