I recommend the novel "The Clan Of The Cavebear". All of the characters are Neanderthals except for the main character, who is...whatever we are.
BTW, the rest of the series sucks IMHO.
Yes,i read a few. The series just keeps getting more and more improbable.
It always was a feminist fantasy series, but it became more and more so later on.
Basically transplanting a modern feminist back 10-20 thousand years ago, and turning her into nearly a goddess.
