Pirates of the Cat Sea. Book 8. Keeper of the Light

What troubles has Jenifur Kotes not escaped on her faithful «Nightmare». Storms, whirlpools — nothing was a challenge for her! Yet luck has turned away from the brave captain: the ship ran aground on the reefs and the entire crew... was cast into the Thousand Mountains — in the very wilderness on the edge of the world. How can she look her crew in the eyes after such a mishap? With a heavy heart, Jen decides to renounce her captaincy and settle in a lighthouse. The local tribe, having learned of this, immediately pays her a visit. And for some reason they treat Jen with great reverence...
Meanwhile, the Sultanate of Gien plans to seize the Thousand Mountains to avenge the disgraceful defeat in the Koshd Skerries. Jen cannot allow this, because now this place is her new home. With a barrel of tar and one cannon, the former captain intends to win a war against an entire fleet. Quite a plan… But Jen has no doubt about her victory!
