Dave--Yes Books on Board does sell new releases, although I just checked and I wouldn't buy Dan Brown's Lost Symbol from them right now. They have it listed for $20.00 right now.

You might want to check out their website.
Also, I notice you're from Massachusetts. The Boston Public Library offers ePub and PDF books for download, and according to their website, anyone living in Massachusetts is eligible to get a library card.
You can even sign up for an e-card on line at:

Their collection of books available for download are available here:

They do have Dan Brown's Lost Symbol available in ePub format, but there is a waiting list for it.
