I have a novel, haven't made it yet, but it's about a girl who's deaf, and named Echo, only for me to find out recently that there is a superhero, who is hearing-impared, named Echo.
Similarly, but not exactly the same, in my novel, "Damsel in the Red Dress," there's one line, in one scene, that's rather similar to a line in a book called "The Bronze Bow," which I don't really care for, but I couldn't help but notice, that that line specifically, is uncomfortably similar to one that appeared in the book.
In the story, there's a boy who's set on vengeance, but he finds himself falling in love with his bffs sister, though he's cruel to her. He once told her she was just a 'pretty child.' then some time later, he witnesses her dancing at a festival, and is enraptured by her beauty, when she asks if he still just sees a pretty child, he admits that he doesn't, and that makes her so happy, it scares him and disconcerts him, he feels the need to keep talking, excusing himself, and ends up hurting her further. Then in my story, there's this:
“Do you remember the night I asked you if you’d like your mother to adopt me?”
He looks at me vacantly, but nods, “Yeah.”
“Have you changed your mind?”
He seems to come to a little bit, propping himself more upright in the chair, he looks at me quizzically.
“Do you still wish my mother had adopted you?”
“No.”
I say it quickly - before I can stop myself- and I see such a brilliant light come into his eyes at that one word - such a cross between paleness and heart-racing - flushing and hope - that I scare myself-
Change the subject.
“I shouldn’t have tried to butt in between you and your mom. It wasn’t my place.”
The light seems to fade out, “Oh,” he says glumly.

So yeah, maybe a little too similar.
