For as long as Fei can remember, there has been no sound in her village, where rocky terrain and frequent avalanches prevent residents from self-sustaining. Fei and her people are at the mercy of a zipline that carries food up the treacherous cliffs from Beiguo, a mysterious faraway kingdom. When villagers begin to lose their sight, deliveries from the zipline shrink and many go hungry. Fei’s home, the people she loves, and her entire existence is plunged into crisis, under threat of darkness and starvation. But soon Fei is awoken in the night by a searing noise, and sound becomes her weapon. Richelle Mead takes readers on a triumphant journey from the peak of Fei’s jagged mountain village to the valley of Beiugo, where a startling truth and an unlikely romance will change her life forever...

Chinese setting. Protagonist's community is entirely deaf and uses sign language. Some people are going blind as well.

St. Vladimir’s Academy isn’t just any boarding school—it’s a hidden place where vampires are educated in the ways of magic and half-human teens train to protect them. Rose Hathaway is a Dhampir, a bodyguard for her best friend Lissa, a Moroi Vampire Princess. They’ve been on the run, but now they’re being dragged back to St. Vladimir’s—the very place where they’re most in danger. . . . Rose and Lissa become enmeshed in forbidden romance, the Academy’s ruthless social scene, and unspeakable nighttime rituals. But they must be careful lest the Strigoi—the world’s fiercest and most dangerous vampires—make Lissa one of them forever.
