The world lies devastated after the massive oil crisis that was described in LAST LIGHT. Human society has more or less entirely broken down and millions lie dead of starvation and disease. There are only one or two beacon communities that have managed to fashion a new way of living.Jenny Sutherland runs one of these groups. Based on a series of decaying offshore oil-rigs - for safety - a few hundred people have rebuilt a semblance of normality in this otherwise dead world.But as her and her people start to explore their surroundings once again, they start to realise not every survivor has the same vision of a better future than their catastrophic past.

Fins into Limbs

Long ago, fish fins evolved into the limbs of land vertebrates and tetrapods. During this transition, some elements of the fin were carried over while new features developed. Lizard limbs, bird wings, and human arms and legs are therefore all evolutionary modifications of the original tetrapod limb. A comprehensive look at the current state of research on fin and limb evolution and development, this volume addresses a wide range of subjects—including growth, structure, maintenance, function, and regeneration. Divided into sections on evolution, development, and transformations, the book begins with a historical introduction to the study of fins and limbs and goes on to consider the evolution of limbs into wings as well as adaptations associated with specialized modes of life, such as digging and burrowing. Fins into Limbs also discusses occasions when evolution appears to have been reversed—in whales, for example, whose front limbs became flippers when they reverted to the water—as well as situations in which limbs are lost, such as in snakes. With contributions from world-renowned researchers, Fins into Limbs will be a font for further investigations in the changing field of evolutionary developmental biology.
