Yes.
Brisinger is the latest book to come out in the inheritence cycle......GREAT BOOK!!
In august 2009, christopher paolini mentioned that the 4th book would have a green dragon on the front cover and that the title of the book would be something that Eragon inherits. The date of release of the book is still unknown. there's more info at shurtugal.com.
Christopher Paolini
I assume you mean the fourth book. As I have typed on other answers before, there is no confirmation that it will be called Empire. Nobody knows what will happen except C.P.
Eragon by Christopher Paolini
Christopher John Oakley has written: 'Ribosome synthesis during the cell cycle of \\'
its because they cycle through their movies
The Lord of the Rings
From what I know, the only dragon alive are Thorn, Shruikan and Saphira (Glaedr doesn't count because he dies in Brisingr, and neither does the green dragon because it hasn't hatched yet).
