In this hardbound edition of novel 23 in this series, Tom must travel to Mars to find out just why the small moon, Phobos, has suddenly begun coming close to the surface. In fact it is coming down to lower and lower orbits that could, within months, endanger the colonists on the planet below. He first tries to use brute force and to push it back into higher orbit, but nearly loses several spacecraft in the attempt. So, he now is faced with finding out the why of it all before he can find a solution that won't mean simply destroying the moon. That, he fears, might backfire and do damage to the colony and the planet. He tries to find some answers with the aid of his Space Friends, but they seem to have disappeared from his life. Without their help he mounts an expedition of Phobos and finds about the last thing he might think of. Now it is a race against time to see if he can rectify the situation and re-place Phobos in its correct orbit.

Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.
