The Prometheus Project is a very good work of science fiction for middle grade kids. To date, there are two books in the series--Trapped (2006) and Captured (2007). My mother first got these to review on her own blog last year, and now finally I have read them.
In Trapped, two very ordinary kids, Ryan and Regan Resnick, move to a very boring town called Brewster, PA--"more like snooze-ter," they think. When they overhear a discussion between their parents about secret codes at the mysterious Protract Company that their parents work for, their curiosity is overwhelming and they decide to go explore the Protract Company for themselves.
What they find is something that is completely out of this world. Really.
The Protrac Company has been been working on something called the Prometheus Project. A bit of history--Prometheus was one of the Titans, who stole fire from the gods and gave it to man. Fire, if used correctly, is very useful. But it can also be very dangerous. The same is true for the secret of the Prometheus Project. Beneath a cloud of trees, in a building whose signs warn of lethal amounts of radioactivity, lies an alien city.
And Ryan and Regan made it through all the security elements (including guards) and gotten into the city, where an accident with a generator kills their mother, and they go back in time. Will they be able to go back and save their mother, or will they be trapped in a paradox forever?
As you can see, because there is a sequel, the answer to this question is obvious...and I'm glad, because I found these books so interesting! The descriptions of the technology, and the technology itself, is fabulous, and the characters are brilliant. Overall, the book is great. I would recommend this to kids who love science fiction, time travel, and things that involve technology, and even people who like non-fiction!
