Elfhame

Holly Black's Elfhame universe — the faerie kingdom that spans two connected series. The Folk of the Air trilogy (The Cruel Prince, The Wicked King, The Queen of Nothing, plus the companion pieces The Lost Sisters and How the King of Elfhame Learned to Hate Stories) follows Jude Duarte; The Stolen Heir Duology (The Stolen Heir, The Prisoner's Throne) follows Suren/Wren a generation later in the same world. Grounded against Goodreads series 352181 and the author's own site (blackholly.com).
