Help me find this book? (details)

I’m almost 100 % certain it was called The Boy From Another Planet. I’ve googled that, and switched planet for world, place, outerspace, anything I could thing of. It was a shortish young adult novel I read in middle school. It was about a boy who never ever spoke or looked anyone in the eye and some girl came around and made him come out of his shell and they fell in loooove. I was thinking about it the other day and I decided I wanted to read it again. I barely remember it, but everythime I search for it, nothing comes up. HELP
