What book should I read next?

[Bow tie and Fez Addict]

So I just went book shopping at Barnes and Nobel and I don't know which book to read first. My options are:
The Hitchhiker's Guide to the Galaxy
I Am Number Four
Partials
Clockwork Angel
Clockwork Prince
Eon: Dragoneye Reborn
Altered
The Sweetness at the Bottom of the Pie

Hitchhiker's Guide, Hands down! But Clockwork Angel is also pretty sweet.
