Voting is now open. There's no need to hurry - the poll will be open until the 15th June, that's four weeks and five weekends.
Do feel free to discuss the selections before making your choice. Try to read some you haven't read yet - at least a chapter or two - before making your choice. I shall certainly do so.
When you've voted, you might also like to vote in
Lynx-Lynx's poll of which books you have read, see
this thread.
Both polls will hide the results until the polls have closed. Note that the polls are not anonymous - people will be able to see what you've voted for at the end of the poll.
