Layla has spent her entire life in the Redoubt, one of the last bastions of humanity in a ravaged world. She's never been beyond the Redoubt's walls; only Crossers, with their special training and survival skills, are permitted to venture into the shadow-haunted wastelands.

When Layla's father falls ill, she knows she needs to find a cure. But no such medicine can be found within the Redoubt. Instead, her only chance is to pass a series of gruelling trials to become a Crosser, and then to strike out into the wilderness.

Seven strangers. One mission. Infinite horror. A man awakes on a boat at sea with no memory of who or where he is. He's not alone - there are six others, each with a unique set of skills. None of them can remember their names. All of them possess a gun. When a message appears on the onboard computer - Proceeding to Point A - the group agrees to work together to survive whatever is coming. But as the boat moves through the mist-shrouded waters, divisions begin to form. Who is directing them and to what purpose? Why can't they remember anything? And what are the screams they can hear beyond the mist? Internationally bestselling fantasy author Anthony Ryan - writing as A. J. Ryan - delivers a nerve-shredding thriller in which seven strangers must undertake a terrifying journey into the unknown.

Polymer science is fundamentally interdisciplinary, yet specialists in one aspect, such as chemistry or processing, frequently encounter difficulties in understanding the effects of other disciplines on their own. This book describes clearly how polymer chemistry and polymer processing interact to affect polymer properties. As such, specialists in both disciplines can gain a deeper understanding of how these subjects underpin each other. Coverage includes step-by-step introductions to polymer processing technologies; details of fluid flow and heat transfer behaviour; shaping methods and physical processes during cooking and curing, and analyses of moulding and extrusion processes.
