I received the message that the U. S. government is hiding knowledge about what is beyond Earth's atmosphere. But all governments hide information from the masses of their people. What intrigued me was when the Sentinel Prime character said to the Optimus Prime character that they used to be gods and now they were called machines. I can relate to that statement. I am a descendant of a people that were performing high sciences at one point in time and now we are beasts of burden. Try to talk to a typical African person about science and see what you get. At best they'll say, how does this help me pay my bills? At worse they'll look at you like you have 2 heads.

i find it incredible that so many people speak so glowingly of this book. on the basis of its literary merit it deserves a prominent spot in supermarket checkout lanes. that this is in any way respected as a novel or thought of as remotely historical (pre-historical, is suppose) speaks sad volumes about our society.i guess my one star may be a bit harsh. it's concievable that one could glean some amusement or light entertainment from this. but i feel a civic duty to in bring down the five star average it's garnered so far.

I first read this book when I was in 7th grade, and am rereading it now, in 11th grade. This is an amazing story that my dad convinced me to read, and I've become hooked on the whole series! Auel gives the reader not only meticulously researced information concerning culture, vivid descriptions of the neanderthals, and geography, but also a twisting, inviting plot that makes the book impossible to put down! Thus Clan of the Cave Bear(and the entire Earth's ChildrenTM series) appeals to a wide audience. Adventure, history, and an eloquent storytelling style are combined with excellent results.
