La Mémoire De Babel by Christelle Dabos

Sent to the colossal, labyrinthine city-library of Babel with Thorn, a young woman must learn to work within the Archives and the fragile politics of a place that stores living memories; as she deciphers manuscripts and uncovers hidden records, she becomes entangled in factional intrigue, betrayals and occult dangers that test her powers, her loyalties and the truth about both the city and her own past.
