Unravel the Dusk by Elizabeth Lim was just released last month. It is the second book in the The Blood of Stars duology (this appears to be the second and final book), following Spin the Dawn which was released last year. And the covers are particularly gorgeous, aren't they?
The books draw upon folklore themes. The reviews reference Mulan and the sewing of dresses of the sun, moon, and stars. I love that challenge in folktales--you most often see it in Cinderella/Donkeyskin variants, but this novel doesn't appear to draw much from that particular tale type. An excellent example of the motif can be found in the Grimms' Allerleirauh.
Book Description for Unravel the Dusk:
Maia Tamarin proved her skill as a tailor when she wove the dresses of the sun, the moon, and the stars, but it will take more than a beautiful gown to hide the darkness rising up within her. . . . The stakes are higher than ever in this breathtaking sequel to Spin the Dawn, perfect for fans of Six of Crows.
Maia Tamarin's journey to sew the dresses of the sun, the moon, and the stars has taken a grievous toll. She returns to a kingdom on the brink of war. Edan, the boy she loves, is gone--perhaps forever--and no sooner does she set foot in the Autumn Palace than she is forced to don the dress of the sun and assume the place of the emperor's bride-to-be to keep the peace. When the emperor's rivals learn of her deception, there is hell to pay, but the war raging around Maia is nothing compared to the battle within. Ever since she was touched by the demon Bandur, she has been changing . . . glancing in the mirror to see her own eyes glowing red; losing control of her magic, her body, her mind. It's only a matter of time before Maia loses herself completely, and in the meantime she will stop at nothing to find Edan, protect her family, and bring lasting peace to her country.
