Not a lot of people know this, but Indiana Jones’s first name must have been Ben. Ben is the fearless and flawless central character in this page-turning Amazonian adventure of the supernatural. His sidekick, Rafael, is neither fearless nor flawless, yet he turns out to be much more useful than you expect. The third of the junior musketeers is Yara, a local girl with a surprisingly good grasp of idiomatic English (“Awesome!”) Throw in a missing Dad, a black jaguar, a nefarious Professor and his henchman, and a complex set of do or die magical tests and you have the ingredients for a full-on, full speed story. It appears to be aimed at 9-11 year-old readers, and the fast pace and excitement should keep them reading to the conclusion. The characters are perhaps a touch stereotypical, and the plot speed and excitement levels completely define the book. This will encourage and stimulate readers to keep reading and be positive about reading more. My own experience of the age group, as parent and grandparent, is that many can engage with more challenging ideas and more depth beyond the thrill of fast-paced narrative, but it’s the author’s book! I will see what the grandchildren think of it without my prejudices and expectations.
