ThiS is not only a book of instruction in chainmaking but it is also a work celebrating man's continuous creativity over thousands of years. At times something that man creates has far-reach ing effects; an example that quickly comes to mind is the wheel, which has enabled many devel opments, from pottery to computers. At this point it is important to note that these same wheels could not have been made without metal tools. From early Neolithic times on gold was a favorite choice in the making of jewelry. During the Neolithic period these "shining stones," probably alluvial, were prized. Actually gold was cold worked as if it were a stone. There is a surviving example of cold-worked gold from Catahuyuk (present day Turkey) estimated to have been made in 6500 B. C. There were only four metals on the earth's surface that were found in sufficient quantity to be used: gold, copper, silver, and meteoric iron. An understanding of the malleability of gold, and of the annealing effect of fire, changed jewelry making; new forms were found. Gold was no longer a piece of stone but a material that could be flattened and made very thin. Sheet and foil are the oldest forms of worked gold. The smiths' tools were stone, wood, and horn.

If an entire nation could seek its freedom, why not a girl? As the Revolutionary War begins, thirteen-year-old Isabel wages her own fight...for freedom. Promised freedom upon the death of their owner, she and her sister, Ruth, in a cruel twist of fate become the property of a malicious New York City couple, the Locktons, who have no sympathy for the American Revolution and even less for Ruth and Isabel. When Isabel meets Curzon, a slave with ties to the Patriots, he encourages her to spy on her owners, who know details of British plans for invasion. She is reluctant at first, but when the unthinkable happens to Ruth, Isabel realizes her loyalty is available to the bidder who can provide her with freedom. From acclaimed author Laurie Halse Anderson comes this compelling, impeccably researched novel that shows the lengths we can go to cast off our chains, both physical and spiritual.

Across race and time, a magical battle for freedom... 1859 Mkembro, West Africa "I know what's going to happen," says Amara as she wakes on the morning of her wedding to discover that she has been blessed -- or cursed -- with the power of prophecy. In her visions, she sees the slaver Van Owen, who will soon arrive on Africa's shores. Her father will challenge the invaders, wielding magic against rifles and whips, and setting in motion Amara's bid for freedom -- a quest that will extend for five generations. But no wait is too long, for Amara can see far into the future. Chains of Time tells two interweaving stories -- Amara's nineteenth century slave chronicle and the tale of her modern-day descendants, all of them fighting to find their voices, their redemption, and their freedom.
