I appreciate everyone who left a comment to enter the giveaway and helped promote it on their own blogs!
The winner was selected with the help of the random-number generator at Random.org, and it is...
Serena of Savvy Verse and Wit!
I will send Serena's mailing address to Josh Henkin so he can send out her inscribed copy of Matrimony, and I'll be looking forward to reading her review of the book.
** And by the way, if you're interested in having Josh Henkin do a phone chat with your book group, the sign-up deadline has been extended to September 30 (although at the time I drafted this post, the website still said the deadline was September 25 - the extension info came from Josh via e-mail).
