This omnibus has the entire Crystal Singer trilogy ("The Crystal Singer", "Killashandra" and "The Crystal Line") in one book.Over all, a 4.5-star trilogy, even though the first book is definitely the best. I guess I'd rate them 5, 4.5 and 4 respectively. I loved reading about how Killashandra learned how to cut crystal in the first one, and her relationship with Lars in the second.I had this book recommended to me because I mentioned liking McCaffrey's Harper's Hall trilogy, so I assumed Crystal Singer would be similar to this trilogy in its atmosphere and descriptions of music. Not so at all! It took me awhile to shake my pre-conceived notions of the book. Not that I was disappointed, it was just disconcerting to expect to read about dragons and thread fall and instead read about spaceships and crystal cutters.That said, I loved the book, as the rating indicates, and would recommend it to anybody who enjoys a good fantasy/sci-fi novel. Crystal singers have a long life-span but cutting also results in severe memory loss, which makes for some very interesting situations. It also made me think - if I knew I was likely to forget everything about my past and everybody I knew... how much effort would I go to to make recordings of my life? What would I willingly forget, and what would I want to remember?
