Giveaways for Hal Junior: The Secret Signal

I'm currently offering 5 signed paperback copies via LibraryThing's Member Giveaway program (currently a 1 in 20 chance of scoring) and another 5 signed copies via Goodreads.

Both giveaways close October 23.

I'm also running a Twitter contest where you simply have to retweet the following to be in the running:

I want to #WinHalJunior with @spacejock http://t.co/hSg90eEH

That one closes 15th October.

Good luck!
