Shannara (Terry Brooks)

The first three books, Sword of Shannara[?], Elfstones of Shannara[?], and Wishsong of Shannara[?] follow Shea[?] and Flick[?] Ohmsford and their immediate descendants. The first book has been criticized for overly borrowing themes from Tolkien's Lord of the Rings.

The next four books known as the Heritage of Shannara[?] are set 300 years after the first book. These follow three of Shea's descendants Walker[?], Coll[?] and Par[?].

The most recent series The Voyage of Jerle Shannara[?] is set around the life of Jerle Shannara.

The prequal First King of Shannara[?] is set during the lifetime of Jerle[?] Shannara, an ancestor of Shea.

The relationships can be seen in the Shannara Family Tree.
