A Winter’s Promise by Christelle Dabos

A Winter's Promise (the first in the Mirror Visitor series) is a French fantasy novel set on a floating island (arc) named Anima that recounts the adventure of a young lady named Ophelia. Ophelia, like everyone else on Anima, possesses a power associated with items in the world. Her ability allows her to "read" an object's past, therefore she curates a museum owned by her grandpa.

Ophelia's hand, meanwhile, has been offered to Thorn, a superintendent and a jerk from another arc; Thorn and his Dragon tribe have considerably more physical and lethal powers than the inhabitants of Anima. Thorn and Ophelia are bonded by a man's desire to comprehend a strong book, for which he wants Ophelia's strength. A Winter's Promise stands out among modern French works as an exhilarating piece of fantasy fiction with superb world-building, cunning politics and scheming, and profound mythology. The politics of Versailles meets Pride and Prejudice in an enemies-to-lovers tale. Layered storytelling and an aesthetic reminiscent of Studio Ghibli, A Winter’s Promise is a delicious French novel.
