It is 2019, the climate in the U.S. has gone just a little bit crazy (snow in New Orleans in June), Eli's father's time experiments have attracted the attention of the government, and to make things worse, Eli's mother has disappeared into a time bubble. Against this backdrop, Eli and his dad make a break for a disintegrating winery in California that dad has inherited, but there's no escaping dad's experiments. Before you know it, Eli has unwittingly become a lightning rod for time, and finds himself shifting back to ancient Alexandria just at the burning of the library, in the company of an intelligent descendant of the dinosaurs from an alternate earth. Does it sound like a lot is going on in this book? Well, a lot is!
It seems these days that most children's science fiction is bogged down in the time travel back to historic times genre that became so popular with the "Magic Treehouse" series. It seems like every sci-fi book released for chldren has this time travel theme. Frankly, I'm tired of it. That said, this is a solid read for children who like the genre. It is well-paced, fairly well written, and pretty well thought out. The only annoying part - no real resolution to the story so that we have to run out and read Dragon Sword: Danger Boy Episode 2 (The King Arthur time travel episode - hey, THAT hasn't been done before about 10 times!). I would recommend this book only to children who really like this type of book - otherwise I think it is kind of run-of-the-mill.
