Katie and David, twins, have lived in the two extremes of life: poverty and wealth. Their parents and uncle worked for years to create a top secret governmental program (called Rover) and once it was completed, they didn't have to want for anything anymore. Except perhaps another family member. Finally, after asking for years, the twins' parents agree to adopt a baby from Katkajan and immediately head off to get her. Unbeknownst to anyone, this is a nefarious plot by the Katkajans to get Rover and suddenly, Katie and David are prisoners in their own home. They decide to escape and try to get to their uncle's remote cabin in Vermont, as he is probably the only one left who can help.
This book has an intriguing concept, especially as it's portrayed as realistic fiction, rather than fantasy, and the plot moves quickly, but is not executed very well. The device of Trixie (the evil Katkajan in charge of the twins) constantly finding the kids every time they escaped or plotted to escape got old (and there are one too many twists, making the book drag a little by the end). Katie and David bicker constantly, which got annoying and felt over-the-top (as opposed to the realistic fighting between siblings it was meant to be). The sudden mood changes also were overwhelming and the overall relationship between the two was irritating. I also found the use of nicknames inconsistent, which was a little jarring to the overall feel of the text. A secondary purchase.
Note: I'm in the minority--if you hop over to the Amazon reviews, you'll see that others have loved it.
