Although Majora's Mask is a direct sequel to Ocarina of Time, there was an official novel released set shortly after the events in the game. "Link and the Portal of Doom" was written by Tracey West and published by Scholastic in 2006 as part of the Nintendo Heroes series.

In the book, a mysterious portal suddenly appears in Hyrule which absorbs all things around it and threatens to destroy the land. Link and Navi have to travel across Hyrule to learn five parts of a song which will destroy the portal.

Although officially licensed by Nintendo, it's considered to be non-canon.
