Ayla is an anatomically modern human (is it technically Cro Magnon? This is set in modern day Ukraine. To the Wikipedia!) orphaned and raised by a tribe of psychic Neanderthals. This one isn't the one with all the doin' it (evidently that is Valley of the Horses which also has a bunch of blonde dudes who shop at Cave-REI), it's the one with a ton of rape and abuse in it.
