Disappointed could not download and I have bees

This book is one of the most informative I've read. The videos are very good and they give a close up image of the inner activity if the hive that is very helpful. Highly recommend!

I made several attempts to download this interactive book. The image of the cover of the book is present on my ipad air but it appears to be incompletely loaded. When I click on the faint image of the book cover nothing happens.
