I want to know if there is anything in literature (english versions or translations are the best) that has shounen-ai in it (but no yaoi and it's not focused on gays' life or something). Best if the main characters are high-schoolers or around that age.

I mean by it that if there are works that are not japanese manga or manhwa or that have nothing to do with Asia at all and maybe are even unknown to asian readers, that have shounen-ai as it's main theme.

Sorry if it's too vague...
Please recommend if you remember something.

Edit: Something sweet like Seven Days would be nice. (Actually, I only like mild shounen-ai...)

I suppose it's not exactly what you want, but this topic lists some really nice books with shounen-ai by English authors. I particularly recommend the Nightrunner series, especially if you like fantasy. There's also this topic, perhaps you'll find something interesting here as well.
