Crystal Singer by Anne McCaffrey Book

     Written in 1982. Has some wear from age.

     Book one of the Crystal Singer Trilogy. Killashandra Ree has spent ten years studying music and training to be a vocal soloist, anticipating interstellar celebrity. After a final exam she learns that a flaw in her voice will prevent her from singing lead. She dreads a life limited to choral work and supporting operatic roles so she plans to exit both school and home planet discreetly. At the spaceport she meets a vital, older man who uses perfect pitch, and his occupational experience as a “crystal singer” on Ballybran, to identify an incoming space shuttle on the verge of explosion. He treats her to a whirlwind romance and the experience of her home planet in ways entirely unknown to her, but sincerely warns her against the high-status, high-income occupation that makes such a vacation possible for him. Further, one of its occupational hazards leaves him in a coma, but Killashandra determines to accompany his return home under life support, and to investigate membership in the Heptite Guild of crystal singers for herself.
