There's a giveaway on Goodreads until July 20th. Three autographed copies of GRAVITY are up for grabs for US residents. Enter and give it a whirl!
International readers: Please note I try to have as many contests available on my Facebook page (and blog tours) open Internationally as possible (I want to be as inclusive as I can), but there are times a contest may be restricted to US due to shipping costs. I hope you understand, and be sure to hang out on my Facebook page to catch the next giveaway!
