Man these books were fucking weird. The first one was pretty close to the movie (or rather, the movie didn't change much), so that was fine. But after that they turn into weird bodice-ripper romances in cro magnon times. Like three-quarters of one of the later books involves her spending an entire year in a cave with a white man and neither of them being able to figure out sex with each other because she keeps bending over and presenting like the neanderthals taught her to do but he comes from a matriarchal cromag society so he doesn't understand her signals and doesn't know he's supposed to "take" her. When they finally figure it out they have crazy wild sex for weeks, then go on a journey and stay in a free-love longhouse where once again mutual confusion gets in the way and she sleeps in a black man's bed while he self-flagellates thinking his jealousy and desire to possess her exclusively is wrong. They eventually reconnect and go on a journey and see some horny elephants in musk and watch the semen ooze freely from their massive turgid dicks and get so horny they start fucking in the middle of the elephants.
