The Girl They Couldn't See — Laurence E. Dahners

This story is about Roni Buchry, a young multiracial girl with dark skin but blue eyes. She faces discrimination in her school and her family's retail business is plagued by an organized crime family that collects “insurance,” often brutally. Roni's always been extraordinarily good at hiding, first in hide-and-seek as a child and later to avoid embarrassment. Now, older, she and her brother begin to realize that what she actually has is a form of telepathy. She can't read other people's minds, or speak to them silently, or force her thoughts on theirs. All she can do is make other people “not notice” her. At first being able to become invisible seems like a great way to hide from or avoid her old boyfriend, but she slowly begins to realize that it will let her do so much more. She even begins to wonder if she might be able to do something about the mob family that's been holding her city in its thrall.
