Memory, Sorrow, and Thorn

Memory, Sorrow, and Thorn is a trilogy of epic fantasy novels by American writer Tad Williams, comprising The Dragonbone Chair (1988), Stone of Farewell (1990), and To Green Angel Tower (1993).

[1][2] Memory, Sorrow, and Thorn takes place on the fictional continent of Osten Ard, home to several united races, including humans, elf-like immortals known as Sithi, and dwarf-like mountain-dwellers named Qanuc.

Simon, ever the mischievous adventurer, accidentally uncovers some of Pryrates' true nature and becomes wrapped into a conspiracy that threatens not only his country of Erkynland, but Osten Ard itself.

Martin has cited Williams' work as a key influence of his own epic high fantasy novel series, A Song of Ice and Fire.

[10] American author Christopher Paolini, writer of The Inheritance Cycle, also cited Memory, Sorrow and Thorn as an influence, calling it "one of the great fantasy epics of all time.
