This week's pick is...
The hardcover is very simple, but I like the simpleness of the cover. I also love how it has an artdeco, 20s feel to it. Now the paperback is a completely different story. It has more of a 50s 'alien invasion' look to it, which does not represent the book at all. Although I admit, it doesn't look as bad as the sequel.
Final Verdict: HARDCOVER
