Deseret Books was the first of the stores to get their online page for Dawn's Early Light up and running, but Seagull should be up soon, and Amazon and most other independent LDS book stores will also have their pages up. Autographed copies will be available through "This Is The Place Bookstore." They're taking pre-orders as are many of your local stores. I'm in the unique position to be able to track shipments of the book, and many of these stores will have books on the shelf by Black Friday and ready for pick-up or shipment. I'll post links to stores with copies in stock as I get that information.
But you can now order online and have copies reserved and sent directly to you.
Have a fabulous Thanksgiving!
