Juliet Marillier writes historical fantasy rooted in Celtic folklore, family loyalty and heroines whose choices are constrained by curses, politics or inherited duty. Daughter of the Forest retells the Six Swans fairy tale through Sorcha, who must remain silent while creating shirts from nettles to save her brothers from enchantment. The Sevenwaters series continues through later generations in medieval Ireland, while the Blackthorn & Grim books combine healing, mystery and dark fairy-tale elements. Marillier's prose is lyrical, romantic and character-led, with folklore and landscape closely integrated into the plot. Her work fits Celtic fantasy, fairy-tale retelling and historical romantic fantasy. Daughter of the Forest is the clearest entry point for her combination of folklore, family duty and slow-building romance. Read more Less
