First Time by Stella Starling is also free right now (and in KU). (Contemporary, high school, coming out, jock/nerd... um, lol. I'm not sure what else to add. Very sweet? Maybe not "YA" since it does have an explicit sex scene, and probably not far enough in the past to be "historical," but it's set back in 2007. It also has a Whispersynced audiobook.)
