I just want to say that hands down Dragoncharm is my favorite book. I remember when I was young reading it in my room, the windows open to the summer air and the roughly used copy smelling of old paper. Those were truly happy days for me, and I am thankful that your book was a part of it.
Don't change it, but if you do, release both original and new edited versions.
It's an understandable temptation - to rewrite and reedit your earlier work.
But fight the temptation. Rewriting is an essential part of the process but only up to the point of publication. Once it's in the public arena, you're in danger of messing with people's cherished memories of your work.
And for the record - Han shot first. In my book, Mr Lucas, he ALWAYS shot first...
No question. Don't change a word.
