Partly due to reader enthusiasm the book is temporarily hard to find online. BUT, while out there doing your last minute shopping, stop in a physical bookstore and check the Science section and you can often find it, as I did a couple of times yesterday. B&N seems to have it in a lot of branches, and several Indy stores*! #giftgivingseason #thedialoguesbook
*Also note that the manager at Cellar Door Books in Riverside says she’d be happy to mail some of her copies to remote buyers!
