I'm looking for a story where Harry's animagus was a phoenix and Draco's was a salamander. The story is told from Draco's POV/3rd person. We don't Harry's animagus form til the end but you learn he can produce and control fire. Draco learns to transform in his form in the Room of Requirements because he doesn't want to used. They start dating after Draco learns of Harry's fire. In the end Harry uses his animagus form to kill Voldemort. Draco is the only one who can withstand the heat to go in the burn site and find Harry. Harry is still in form as a baby phoenix but transform back to himself in the end.
I hope some one can remember this story. Thanks
