Additional info the cover has a dragon and a huge sword and I think the dragons name is wilda or something like that im at my wits end. Im pretty sure the author was also a teen ay the time of writing

Eragon?

The dragon's name is Saphira, and the author was a teen at the time of writing, but I'm not sure the rest matches.
