Titan Magic - Titan Magic, #1

Mute, heartless, and tormented by auditory hallucinations, Madeleine Lavoie never questions why her family has hidden her from the world. But the night her brother casts her out, she learns the mysterious voice she thought existed only in her mind is no delusion, and no matter how hard she tries, she can never disobey it. Now Madeleine must find her own voice in a cacophony of powerful tyrants, monsters, and gods.
If she fails, she will forfeit her life and the lives of everyone who loves her. But if she succeeds, she may finally gain the ability to love someone in return.
