The Wishsong of Shannara is an epic fantasy novel by American writer Terry Brooks. It is the final novel in the Original Shannara Trilogy, with the other two being The Sword of Shannara and The Elfstones of Shannara. The story revolves around Jair and Brin Ohmsford, the children of the main characters from The Elfstones of Shannara: Wil Ohmsford and Eretria. The siblings, each possessing an inherited magic, must save the Four Lands from the evil magic within a tome called the Ildatch. Plot summary Prelude Before the dawn of mankind, Demons created a book of dark magic, called the Ildatch.
