I NEED HELP FINDING A STORY!!

OK I REALLY need your help! A few months back I read a story about a human who was adopted by the griffon king and queen. He is in a relationship with Gilda and had sex with a dragon named Ellie. He has a best friend named "Rush" and he was part of some elite griffon army but was discharged. The main antagonist is named somewhere along the lines of "Alvonich" but it's a bit longer than that. I believe the human's name was Xavier or something. Despite knowing all this I cant find the story ANYWHERE so if any of you know what I'm talking about then PLEASE PLEASE help me out. Thank you very much in advanced!
