Launched just weeks ago, Moving Christmas, A Frank Duffy Adventure has already proved quite popular in the App Store. The 65-page interactive book tells the story of what happens to the North Pole when global warming hits. Now, AppAdvice is pleased to offer some free promo codes for the e-book, just in time for the big holiday.

Created by Trusted Cape, the book is the first-in-a-series of children’s books that will star Frank and his immovable dog, Bricks. In it, Santa and his not-so-merry elves must move their village to the South Pole where the ice caps are melting more slowly. But they must hurry, Christmas is on its way.

Each page is filled with beautifully drawn characters and scenery, whimsical interactivity, and of course, tells an eco-friendly message. Plus, it is also quite funny for kids (and adults) of all ages.

The e-book is available in the App Store for $2.99. A full-color print version, “Moving Christmas: A Frank Duffy Adventure (Volume 1),” is available for $12.99 through Amazon.
