Prices range from $3.99 for a Step Into Reading title to $13.99 for the interactive edition of I Love the Nightlife!. Also releasing this week is the first-ever Dr. Seuss coloring app, Dr. Seuss's The Cat in the Hat Color & Create (for iPad), with 16 pages to color, at an introductory price of $1.99. Tools include animated effects, crayons, paint brushes, stickers, a tap-to-fill paint bucket and more. Additional e-books will be released in the fall.
