Books like Crystal Singer

I read this book as a youth and loved it, but reading it now at age 45 it does not quite hold the same appeal. I see a woman that is hell-bent on remaining without attachments. She is very bright and talented, but remains aloof emotionally (the come-and-go sexual relationships), socially, psychologically (huge ego), physically (her choice of profession). Originally the high achievement in a difficult occupation was fascinating, a work that required all sacrifice--something I dreamed of myself. Now, however, I have found the importance of relationships and a social life unlike at any other time in my life, and know that the career and high achievement may need to be sacrificed for these things I deem more important. The story is well-written, Killa is an interesting well-drawn, but the story no longer speaks to me. I may not even finish it this time around.
