Just a few posts ago, brothers Diego and Pablo showed us the 39 Magic Treehouse books by Mary Pope Osborne that they read over the summer. Now they have had an even greater adventure: meeting the author herself! What a thrill it must have been to meet their favorite author at Boswell Books and have two of their books signed! They also got to vote on a theme for her next book and were able to ask her questions. Here are Diego and Pablo with Mary Pope Osborne and her sister, Natalie Pope Boyce (author of the Fact Checker series). What a special treat!
