The Age of Extinction

In a future Earth where dragons reign supreme and have only each other to fear, is there any chance left for peace?  A conflicted dragon. A Prophecy. And an ancient wyrm with a dark secret...  In the aftermath of a disastrous showdown in Japan, Gravv and his sire travel to meet with potential allies in the west.  But those allies have plans of their own, and all is not as it seems.  Will Gravv find a way to rise above his own prejudices and overcome the machinations of new enemies, or will The Age of Extinction prove aptly named?
