Seeking to avenge the murder of her true love while on a dredge ship searching for gold, fifteen-year-old captain Poe Blythe becomes the architect of new defenses designed to destroy her enemies.

Poe Blythe, the young captain of the Outpost's last mining ship, wants revenge far more than the gold they tear from the Serpentine River. She has vowed to annihilate the river raiders who robbed her of everything two years ago. But as she navigates the treacherous waters of the Serpentine and realizes there might be a traitor among her crew, she must also reckon with who she has become, who she wants to be, and the ways love can change and shape you. -- adapted from jacket
