HarperCollins Children’s Books is opening up digital storefronts for its I Can Read children’s reading book series in both the iBookstore and in the Nook Bookstore. The collection will have its own boutique in each of these digital bookstores.

The eBook series includes more than eighty titles of learn-to-read books such as Biscuit; Frog and Toad are Friends; and The Berenstain Bear’s Class Trip. The eBook versions of the books include additional elements such as a read-along track and sound effects that are synced to a word or page.

The eBooks are priced at $4.99 in each of the digital storefronts and both stores also feature a free digital copy of Dixie by Grace Gillman, a Level 1 book from the series.
