Good Greek Mythology

Does anyone know of good places to find stories of greek myths that are large enough to have substantial conversation about in class? I am planning on using these stories in between books or as small contained lessons in the classroom between units. I don't want an infantilized version of the story, but also don't want full on books like Percy Jackson. I am mainly looking for short stories (8-15 pages preferably).

I am having trouble finding good resources that tell the story well and are detailed.

If anyone could point me in the right direction that would be great!
