This is from an advance review copy for which I thank the publisher.
Despite the fact that I am rating this as a worthy read, because for young and inquisitive kids I don't doubt that it will be fun and educational, I have to say that I saw little point in sending this book out as an ebook for review purposes without the accompanying colored 'lenses', because without those three lenses, whether this book is print or electronic, you are completely unable to gage the quality and utility of the images!
Those pictures are printed in three colors, and when viewed through of one the three lenses, red, blue, or green, reveal different things. For each continent ion this atlas, red revealed cultural highlights, blue revealed natural wonders, and green revealed the continental outline and surrounding ocean.
I am not a professional reviewer. I don't get paid for this. I don't even ask for thanks (and rarely get it!) for any of the getting on for three thousand reviews I've posted on this blog. I review books because I love books, and because I think good books deserve promotion, especially when they're aimed at children. So I do not merit print versions of books even when they're designed as print books.
All I get is the ebook, and in order to fully review this particular one properly, I had to do a screen-capture on a couple of images, import then into an art program I have, add a transparent layer to it, color that layer in each of the three primary colors in turn, and then reduce the opacity of that color by 25% in order to see the image below and gather what it is I'm supposed to see when the reader looks at these pages through one of the colored lenses. Consequently I did not do this for all images! I did get the picture though - literally - and it's quite fund when viewed not just through that lends, but through a child's eyes. It's rather reminiscent of that 2004 movie National Treasure where the trio is looking at the map thorough the different colored lenses of Ben Franklin's spectacles.
So again, while I wonder what the publisher was thinking in issuing this for review sans lenses, and while I'd personally have some reticence about buying a book which has not one, but three separate additional and crucial components to it, any one of which could become lost and spoil the experience, I still have to say that I consider it a worthy read provided you can use the lenses (or fashion an adequate substitute for any that get lost). It's fun for kids to explore things by themselves and take control of their reading experience, and it is magical to discover how light can hide and reveal secrets.
