The Final Warning (Maximum Ride, Book 4) by James Patterson
This was the fourth book in the Maximum Ride Series and it was pretty good. There was less action and less swearing, but there was also a lot of talk about the Gren House effect. That seemed to be the main theme of this particular book in the series. So heads up for any pro/anti Green House Believers.
In the book, Max and her flock go to Antartica to study the effect of Green House Emissions. In between penguins and talk of melting ice caps, her flock gets captured by an evil scientist who wants to sell the flock to the highest bidder. But during the auction a tornado rips through Florida causing untold destruction and allowing the flock to escape.
