Voiceless (Voiceless Duology #1) by E.G. Wilson
Adelaide Te Ngawai was thirteen when Maunga Richards stole her voice.
Addy is plunged into silence when a high school bully inflicts her with an incurable disease that leaves her unable to speak, write, or create. Vox Pox—a man-made malady that’s been terrorizing the city for months. Resilient, Addy fights to survive. To not be silenced. But then her brother, Theo, is infected as well.
Desperate for any information that might help cure Theo, Addy follows Maunga into a newly developed virtual psychoreality simulator and discovers a conspiracy deeper than she’d ever imagined. How far will she go to save her brother?
