Juliet Ferrars kid

This is Juliette Ferrars but as a kid, I think that’s how you spell her last name and I’m sorry I spelt her name wrong in the title or if you thought something different by the title, I don’t really know what Juliette looks like, I’m like halfway done with the 1st book, so let’s just say brown eyes, long brown hair, and is skinny. She’s 3 (I either forgot what she said or am guessing) and she finds out about how if she touches people something bad happens to them. And she barely eats and talks to no one but herself
