Comprehensive, yet concise, this updated and expanded edition of Orthopedic Secrets uses the familiar question-and-answer format of the Secrets Series. It covers virtually every area of orthopaedics in its approximately 100 chapters and should be useful for clinicians as a refresher or for students as a review for oral exams. Ten sections divide material into general topics, congenital and developmental disorders, and specific anatomic regions.

Every two hundred years or so, shimmering Threads fall from space, raining death and black ruin on Pern. The great dragons of Pern hurl themselves through the beleagured skies, flaming tongues of fire to destroy deadly Thread and save the Planet. But it was not Threadfall that made young Menolly unhappy. It was her father who betrayed her ambition to be a Harper, who thwarted her love of music. Menolly had no choice but to run away. When, suddenly, she came upon a group of fire lizards, wild and smaller relatives of the fire-breathing dragons, she let her music swirl around them. She taught...

When Menolly, daughter of Yanus Sea Holder, arrived at the Harper Craft Hall, she came in style, aboard a huge bronze dragon, followed by her nine fire lizards. The Masterharper of Pern, aware of her unique skills, had chosen her as his only girl apprentice. But the holdless girl had first to overcome many heartaches in this strange new life. Two things sustained her -- her devoted lizards, a subject on which she was fitted to instruct her Masters -- and the music...music of compelling beauty, music-making where at last she was accepted. In the Great Hall, Menolly could fulfil her destiny.

Of all the young singers at the Harperhall of Pern, Piemur was the one chosen for the leading role at Lord Groghe's Gather...and then his voice broke. Suddenly his whole future at Harperhall became uncertain. But Masterharper Robinton, Menolly and Sebell had other plans for Piemur. They were sure that his quick wits and discretion could be used to keep a check on the troublesome Oldtimers and their strange traffic in fire lizards. So, whilst serving as a messanger-drum apprentice, Piemur carried out special errands for the three. And it was on one such errand that he realized his wildest...

Some fourteen hundred turns after men first came to Pern rode Moreta, on her great golden dragon, Orlith. It was towards the end of the Pass of the Red Star -- a time when every living creature on Pern was threatened by Threadfall -- when the courage and daring of dragons and their riders was all that kept the planet from extinction. And then, at the height of the battle against Thread, came a new and terrible evil. Moreta, in one last superhuman endeavour, was to save her people, and become the greatest legend of dragonlore until the end of time.

The renegades were the misfits, the outcasts and the murderers united by Thella, Lady Holder of Telgar. They began a reign of terror as they moved from theft and murder to vicious and insane revenge.

Led by Masterharper Robinton and F'lar and Lessa, the people of Pern excavate the ancient remains of the planet's original settlement and uncover the colonists' voice-activated artificial intelligence system.

Five episodes in the history of Pern, from the very first space survey recommending colonization, to the last, where the early world, its young dragon culture undetected, is condemned to be isolated in space. Anne McCaffrey has won both the Hugo and Nebula awards.

Young Kindan has no expectations other than joining his father in the mines of camp Natalon, a coal mining settlement struggling to turn a profit far from the great holds where the presence of dragons and their riders means safety and civilization.

When Masterharper Zist takes over as Harper for Natalon's coal-mining camp, he takes with him his apprentice, the orphaned Pellar, and Pellar's fire-lizard Chitter. Pellar has become a gifted tracker and Zist gives him his own mission - to find out if the thefts of coal are the work of the criminals condemned to a life of wandering and hardship.
