[TOMT] YA book about greek gods on mountain

I read this book in middle school about gods who lived on a mountain, i guess based on mount olympus and greek gods. i don’t remember much of the plot just that a young mortal girl was the main character and it was supposed to be back in ancient times. i remember it was fairly slow-paced and atmospheric, with an emphasis on the divide between the gods and the regular people (she might have been a farmer)? eventually, i’m pretty sure she visits mount olympus. thanks!
