BlueWizard, I totally agree about Kay's storytelling, it just rounds out the whole story completely and answers a lot of questions and is just a great read.
Ashley, I suppose Kay's novel does stand by itself and you certainly can understand without reading the original, though I read it after reading the original, and it kind of fills in a lot of blanks and I found it to be fun to see the different spin on it and how it intertwines with the novel and all the characters and such. I liked the experience of reading this one after the original, but I suppose you could read it without the original.
Liz, I never heard of Progeny and Phantasy. Are they sequels or something to this novel? If so, I think I'll have to read those too. And also Liz, I think "Phantom" is out of print, I recommend trying your local library, that's where I got my copy. Good luck!
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
