It is curious that one one the more significant achievements of "Pastor" Charles Taze Russell is omitted above. That fact is that he was the primary founder of the Watchtower Bible and Tract Society, and the religion now known as "Jehovah's Witnesses." No small amount of his theology is controversial in the body of the Church as a whole, as it would be (for different reasons, perhaps) amongst Jehovah's Witnesses.

Ex Output:

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.

Negative

I really liked this book...it is one of my favorite nightworld books. I think that it was sad that Thea had to leave her family and live with Eric and his mom but I don't think they had much choice.. anyway it's great! And I enjoyed reading it as much as I enjoyed reading the rest of the Nightworld series..by the way I think that L J Smith is the best!!! Anyway gotta go!!

Ex Output:

Positive
