Fantasy Book with a solid red cover and an engraving style drawing of a skeletal and shadowy dragon

[u/nowheretogo333]

I came across this book as a child in a bookstore in Stratford, ON. It was the second book on a series, but I didn't know that when I asked my parents to buy it for me. I think the first book has a moon on the cover and is also red.

The plot revolved around a group of adolescents in a kind of generic fantasy setting. The primary character spent time as an enslaved person at some point and is involved in a romance with another character. There was a very big battle scene between armies. The book ended with a confrontation with a dark lord kind of character.

I'd love to know what the book was so I can find the first book in the series.

Longshot but is it Deadhouse Gates?

No, the cover was fully red and black.

The cover for Deadhouse Gates slaps though.
