In The Time Traveller's Journal, Prospero Hermes manages to time travel as far back as prehistoric times and into the future armed with little more than an orbitator - to tell him where in the world he is and whether he's going forward or backward in time - and a relatively rudimentary time machine.
Time travel as a plot device has been done before and quite effectively, in the case of the Magic Tree House series for kids. While The Time Traveller's Journal trods some of the same ground as the Magic Tree House books - dinosaurs, mummies and adventures on the moon - the former's use of the first-person narrative gives it more of an eyewitness feel and helps to bring the history to life.
Kids who might otherwise shy away from history may be drawn to this interactive book with its pop-ups, diagrams, pull-outs, drawings, journal-like entries (made to look authentic with a few scratch outs) and even a mirror that's useful for deciphering reversed-image text. Greg Becker's illustrations are beautifully laid out, varied, and evocative of a style he likely honed working at Dorling Kindersley (DK Books). You might even mistake The Time Traveller's Journal for a worn photo album were it not for the pocket-watch-sized orbitator hologram on the cover.
Prospero Hermes' time machine takes him to the Cretaceous period shortly before dinosaurs became extinct and then propels him forward millions of years into the Stone Age, Ancient Egypt, the Italian Renaissance, the South Pole and the moon, before catapulting him into the future. The author steers clear of religion and wars, save a brief mention of the Spanish conquest of the Inca Empire.
Prospero Hermes is introduced as an Edwardian man. Why the author chose to be the embodiment of a man from a century ago is anyone's guess, but perhaps it's linked tangentially to King Edward VII's (son of Queen Victoria) fondness for travel. Prospero Hermes could just as easily be the pseudonym of a curator at the British Museum as the book includes many items that are part of the Museum's collection.
The Time Traveller's Journal is written from a western perspective, which may explain why you won't find any mention of the Sumerians, the Phoenicians, the Babylonians or the Chinese among others. You could perhaps argue, in the case of the section devoted to British explorer Captain James Cook, that the book is a tad British-centric as Cook doesn't readily leap to mind when one thinks of great explorers.
Were it not for the use of cursive writing throughout most of the book, I would recommend it to kids as young as five years old. All in all, the book is very well laid out and provides an engaging survey of key historical events.
