[EX Q]: Steve Milloy, author of this book, is a Washington, DC, lobbyist who has represented just about every polluting industry imaginable, especially the tobacco industry. If you doubt this, read the book Trust Us, We're Experts! by Rampton and Stauber, who have pages on Milloy, CATO, American Council on Science and Health, and their PR campaigns to smear health and environmental concerns as 'junk science' waged by evil public interest groups and activists like Ralph Nader. Pure industry propaganda.
[EX A]: Negative

[EX Q]: This is the story of the brother of one of the secondary characters from the Leopard Lord. Farris is sold as a slave by his stepfather. Claimed by two very different gods, his fate will be decided on what he does with his life. Will he be ruled by vengeance and violence? Or will his love of the animals he tends lead him to a different choice? Ms Morland's characterization is excellent, the plotting is much improved (from good to even better). If I had a complaint, it would be that this book did not sweep me into a different world the way that the very best speculative fiction does. However, that said, it was a most enjoyable read, and I'll buy her next book, too.
[EX A]: Positive

[EX Q]: THis company advertised this as a 3D movie. When I received it it was only a Blu-ray. They told me I would have to ship it back to them to prove it. I was very upset and they are horribel to work with.
