Random.org has spoken (more or less) and chosen entrant number 228 -- Robin.
Robin has chosen World of Warcraft: Dungeon Companion II. I got a new one at The Book Depository and it should soon be on its way. I've got to say that this one is a complete mystery to me. I am not a gamer and don't quite get it. I hope Robin enjoys the book.
I would like to thank all 235 people who entered. I'm sorry I couldn't choose all of you. I do have another contest that you can enter if you wish. I will be giving away a finished copy of The Girl Who Circumnavigated Fairyland in a Ship of Her Own Making by Catherynne M. Valente. You can get all the details and fill out the form here.
