Apps by Auryn, a childrens' book publisher, is making a different one of their interactive ebooks free per day, for the month of March, to honor National Reading Month. If you have kids, you've probably either heard, or own some, of their titles. They offer nice, quality tales. The Little Mermaid by Lisbeth Zwerger was free on Friday, March 1st. 4th of July was free for Saturday in celebration of National Anthem Day. Edsel McFarlan's New Car was free on Sunday, and Hattie, the Backstage Bat by Don Freeman is free today. Definitely worth checking out if you have kids!
