Killashandra Ree has spent ten grueling years in musical training, anticipating interstellar celebrity as a vocal soloist. She is young, beautiful, and still without prospects. After learning that a flaw in her voice will prevent her from singing lead, she hears of the mysterious Heptite Guild on the planet Ballybran, where the fabled Black Crystal is found. Mining this strange form of crystal is a dangerous occupation but to Killa, the risks are acceptable. Remarkably, her adaptation to crystal mining is unusually rapid and easy and Killashandra advances quickly. The problem is-few people who land on Ballybran ever leave.
