Drowned Ammet is a fantasy novel for young adults by British author Diana Wynne Jones.

Mitt's father joins the Free Holanders, a resistance against the Earl Hadd.

Mitt was convinced that three of the Free Holanders betrayed his father to the Earl's soldiers.

Hildy and Ynen decide to run away on a magnificent new boat, the Wind's Road.

The three find, floating in the sea, a wheat figure of Poor Old Ammet.

Mitt has a small wax figure of Poor Old Ammet's consort, Libby Beer, which they attach to the stern.

Mitt's father commandeers the boat, then forces them to sail to the Holy Islands.

Libby tells her that, if she wishes to return to the Holy Islands, she must trust Mitt.

On the Holy Island, Mitt encounters two demigods, Old Ammet and Libby Beer, in person and learns their secret names.

Mitt's father is taking Ynen and Navis back to Holand, but they are to be killed by the new Earl.

Mitt invokes the greater name of Libby Beer, causing an island to rise up, destroying the boat.

Mitt promises Poor Old Ammet that someday, he will return to Holy Islands as a friend, not as a conqueror.
