Crystal Singer Series by Anne McCaffrey

Her name was Killashandra Ree. And after ten grueling years of musical training, she was still without prospects. Until she heard of the mysterious Heptite Guild who could provide careers, security, and wealth beyond imagining. The problem was, few people who landed on Ballybran ever left. But to Killashandra the risks were acceptable....

At first Killashandra Ree's ambitions to become a Crystal Singer, get rich, and forget her past, were going just as she had hoped. But after she grew wealthy, a devastating storm turned her claim to useless rock. In short order she was broke, she had crystal sickness so bad she thought she was going to die, and the only way she could be true to the man she loved was to leave him....
