Saving the World and Other Extreme Sports by James Patterson

The time has come for Max,Fang, Iggy, Nudge, Gasman, and Angel to face their ultimate enemy and, despite many obstacles, try to save the world from a sinister plan to re-engineer a select population into a scientifically superior master race.

Better than book 1, not as good as book 2, but I'm still interested.

This series seems a little juvenile, but it is from the point-of-view of a 14 year old who didn't grow up like anyone else on the planet (besides her 4 ‘siblings') but I like the ideas presented as well as the well developed character personalities. Though it may be a little hard to read if you're picky or get bored with easy reads, but I'd say that these exciting adventure novels can be worth it.
I do hope this isn't the last book in the series.
