a question of what to read

So. I have two readings at Worldcon, each about half an hour. So I need
to come up with two different things to read.

My brain is not up to this challenge. So I'm asking for opinions.

Should I read:

a chapter from STAYING DEAD
one of the Wren & Sergei stories forthcoming in October
something from the second Retrievers book, CURSE THE DARK
a chapter from the WiP, a YA fantasy novel
One or more stories from the Dragon Virus series (more SFnal with edge of horror)
One or more stories from the Portside series (SFnal and somewhat literary)

?

Opinions being solicited, so speak up...
