If you devour tales with fickle characters like faerie kings (Maas) or Slavic witches/vedma (Houston), you might enjoy both of these, but also Emily Wilde’s Encyclopedia of Faeries. Favorite lines, the wedding vows in The Bone Roots: “I promise to be with you as long as you’ll have me, and to keep my word to you and your secrets for as long as my shadow is long. . . I promise to share with you in good luck and bad, and to never willingly bring sorrow into your life.”
