Far in the future, the merchant ships of the Space Trading Commission fleet travel the space lanes each on journeys of trade and exploration. As the Phoenix falls through a crack in the sky after completing one of its many n-space jumps, First Officer Jana Maines makes an astounding discovery. Jana detects a derelicta ghost ship from the forgotten past. Believing this to be an opportunity to advance her career and financially help her parents, Jana attempts to convince her captain that they should investigate, but he insists that they remain on course. Just as they are about to depart, however, a signal is received from the shipand Janas adventures begin! A routine resupply run to a lonely desert world becomes complicated when more than one man expresses greater interest in her than her ships cargo. While on a mission from an ocean world, she desperately tries to find a way to save millions of fish eggs critical to the survival of an entire planet. Her encounters include an astonishingly ancient woman, a wealthy mystic, and a string of crusty, opinionated captains. In a series of science fiction stories that span the far reaches of the universe, a courageous captain-in-training faces challenges that test her abilities to the limit as she strives to complete her missions.

This retrospective collection of stories from all phases of Niven's writing career is rich with gossip, storytelling vigor, and sheer science-fictional play.

Surgery theory, the basis for the classification theory of manifolds, is now about forty years old. There have been some extraordinary accomplishments in that time, which have led to enormously varied interactions with algebra, analysis, and geometry. Workers in many of these areas have often lamented the lack of a single source that surveys surgery theory and its applications. Indeed, no one person could write such a survey. The sixtieth birthday of C. T. C. Wall, one of the leaders of the founding generation of surgery theory, provided an opportunity to rectify the situation and produce a comprehensive book on the subject. Experts have written state-of-the-art reports that will be of broad interest to all those interested in topology, not only graduate students and mathematicians, but mathematical physicists as well. Contributors include J. Milnor, S. Novikov, W. Browder, T. Lance, E. Brown, M. Kreck, J. Klein, M. Davis, J. Davis, I. Hambleton, L. Taylor, C. Stark, E. Pedersen, W. Mio, J. Levine, K. Orr, J. Roe, J. Milgram, and C. Thomas.
