On the promontory of Kinnaird Head, on the north-east coast of Scotland, sits a peculiarly designed lighthouse. It is an exception in history - the only lighthouse in the world to be built into a castle. Originally constructed in 1571 by Sir Alexander Fraser, the castle towered over his new town of Fraserburgh with Scotland's forgotten university built in its shadow. For 200 years this small tower played host to lairds, lords and Jacobites before abandonment in 1750. The castle was saved from ruin in 1787 when the newly formed Northern Lighthouse Board transformed it into their first Scottish lighthouse. Every Stevenson engineer visited and left their mark on the site, while a never-ending watch of keepers kept the light flashing for 200 years. With automation in 1991 there was a second abandonment of the old tower, until it made its latest transition from lighthouse to museum. Since 1995 it has been Scotland's most visited lighthouse, frozen in time as a monument to the manned lighthouses of old.

Visitors to South-East Asia are usually astonished at the profusion of marine life that exists in this biodiversity hot-spot. Reef Fishes of South-East Asia is a comprehensive and easy-to-follow guide to this rich diversity. Covering the waters off the coasts of Thailand, Hong Kong, China, Malaysia, Taiwan, Singapore, Indonesia and the Philippines, this compact book, illustrated with vibrant colour photographs, is an essential companion for anyone interested in the undersea world, from the casual snorkeller to the most experienced diver. It includes concise descriptions of 270 species of fish, corals and invertebrates, accompanied by 300 full-colour photographs, and information on habitat, diet and behaviour. Clear line drawings are provided for quick identification of fish families, and a short introduction covers reef conservation and practical tips to help you get the most out of your visit to the region.

Before the age of the lighthouse Scotland's untamed seas and perilous rocky coast too often witnessed the watery end to the mariner's voyage. From its establishment in 1786, it was the remit of the Northern Lighthouse Board to tame these harsh seas with the building of guiding lights around Scotland's rugged coast 'For the Safety of All'. The history of Scotland's lighthouses would be dominated by one family of engineers. For its first 150 years, the NLB would be shaped by four generations of the Stevenson family as lighthouse builders, innovators and inventors. From humble beginnings at Kinnaird Head, this family would perfect the engineering marvels of the Bell Rock and Skerryvore, and pioneer wireless technologies into the modern age. The lighthouse story is also one of habitation on the Stevensons' creations on the extremities of civilisation as the light-keepers, and their families, lived and served on the wind-battered terrain of Scotland's edge. It was a story of survival, a unique way of life, which came and went within the pages of this history. The technological breakthroughs which began with the Stevensons advanced to automation and the end of the light-keeper. Nowadays the lights still flash, but there's nobody there.

Since its completion in 1811, the Bell Rock Lighthouse has been revered as an industrial wonder of the world. The iconic tower was built on the Inchcape Rock, a submerged reef some 12 miles off the coast of Arbroath, and now stands as the oldest sea-washed tower in the world, surviving over 200 years of violent storms and crashing waves. The construction of the Bell Rock made the name of the Stevenson family, a dynasty of lighthouse engineers who dominated Scottish lighthouse engineering for 150 years. Robert Stevenson was the first man on the reef and the last man off, a personal commitment which saw the Bell Rock's actual Chief Engineer, John Rennie, almost deleted from the building's history. The Bell Rock is, however, more than just Stevenson and Rennie. Not only was it a remarkable feat of engineering, but one which played host to a remarkable way of life. The light-keepers undertook nightly vigils on the rock for 177 years, their often mundane and monotonous duties occasionally being punctuated by technological improvements and world events. The keepers are now all gone but the Bell Rock continues to show its familiar flash for the safety of all.
