What's the Name of That Book??? discussion

Read around 2013? Society is obsessed with beauty and beautiful singing. Main character is not considered beautiful, she is too tall and her face isn't "attractive", but her voice is among the best ever heard. I don't believe anyone knows that she can sing. She learns she can "cast" her voice across a space and make it sound like she's singing from places she isn't. She ends up using this to help the elite society believe that a beautiful betrothed woman (who may or may not be related to her, I don't remember) is a really good singer. Turns out this betrothed woman is faking her beauty as well as her voice. The main character meets non-human characters at some point (trolls maybe?) who reveal that she's partly one of what they are, and that they find her beautiful because her black hair is actually a color that humans cannot see that this species finds very attractive. Someone tries to kill the main character with a poisoned apple that gets stuck in her throat.
