So, someone on the message board made a comment about a boxed set, which reminded me that I have updates for you all...
First up: Token of Darkness has a release date, February 9, 2010. If you're the right kind of person and in a relationship, you can remind your sweetheart that books make great gifts. If you're not in a relationship, you can remind anyone you want to feel guilty that books are a great gifts to keep you from harassing them during their dates. ;)
Next up: Random House is in fact releasing an omnibus edition including the first four Den of Shadows books. It's called the Quartet, and should be on sale August 11, 2009.
Edit: Target has agreed to pick up the Omnibus to distribute!
