This is a large-format book with full-page illustrations, a description of the Seven Wonders of the World from ancient history jazzed up with with a rather weak and contrived story.
I think the fictional element could have been dumped in favour of a more detailed description of each "wonder" as the story adds almost nothing.
The large illustrations are certainly bold but of uneven quality; while The Statue of Zeus and The Lighthouse at Alexandria are striking images, the Hanging Gardens of Babylon are pretty feeble - more shopping mall than Kew Gardens!
