The Black Wall [EPUB ebook] 

When Syrina finds Anna and Pasha, survivors of General Mann’s assault on the valley hidden in the peaks of the Black Wall, she realizes they may be the key to discovering what she is. But after feelings she didn’t think possible well up for Pasha, things grow complicated.
With the help of Ves, pirate-turned-smuggler, they pursue Mann across the continent. However, growing tensions between factions within the Church of N’narad make the trip more perilous than they counted on.
Can Syrina find the key to herself and the voice in her head, and find revenge against her master? And what price will she be willing to pay?
