The Heart of What Was Lost

Plot summary
After Ineluki the Storm King's fall in "Memory, Sorrow, and Thorn", his followers, the Norns, flee the lands of men and retreat north to their ancient city of Nakkiga. As the Norns make their way to their land in the Nornfells, the Rimmersman leader, Duke Isgrimnur, leads his army in pursuit, determined to destroy the Norns and their ancient Queen Utuk'ku once and for all.

The book is told from three points of view: Duke Isgrimnur of Rimmersgard; a Norn leader, Viyeki; and Porto, a Perdruinese mercenary.

Reception
Jason Heller, a book reviewer for NPR, reviewed the book, stating the novel balances "warmth with grimness, and gentle bits of humor with violence and vengeance. Williams has tapped back into the dynamic that made "Memory, Sorrow, and Thorn" so absorbing." Aidan Moher at Barnes & Noble's fantasy blog called The Heart of What Was Lost "a glorious return to a landmark work of Epic Fantasy".
