Tallynd

Tallynd du Boll is a Brynt tidal mariner. She severely hampered the initial Bone Giant invasion of Pelemyn, warned other cities along the Brynlon coast, and eventually obtained the Bone Giant documents. For her services, she was promoted from Gerstad to the new rank of Second Konstad.

From the author's website:"Tallynd is a soldier who has already survived her toughest battle: losing her husband. But now she finds herself on the front lines of an invasion of giants, intent on wiping out the entire kingdom, including Tallynd’s two sons–all that she has left. The stakes have never been higher. If Tallynd fails, her boys may never become men."-from https://kevinhearne.com/books/a-plague-of-giants/
