What to Read Next?

I'm in the process of finishing up two books: Kim Stanley Robinson's fantastic 2312, and Brian Greene's The Hidden Reality when I get an uninterrupted stretch of time. However, i'm already eagerly looking at the books awaiting me on my kindle and bedside table, which include:

• Margo Lanagan'sRed Spikes
• Denis Johnson's Jesus' Son
• Jim Dodge's Rain on the River
• Compilation of Short Stories: The Secret Hidden History of Science Fiction
• Alastair Reynolds's Pushing Ice
• Allison Rossett'sFirst Things Fast (for a book club at work)
• Karuna Cayton's The Misleading Mind

Have you read any of these before? Any recommendations about what I should pick up next?
