Killer Aliens vs. Badass Teens! (The Water Bear Cycle, #1)

Mari Cruz and her friends are bored to death with their town in the New Mexico desert.  When an alien Arbitrator shows up to decide the fate of the Earth, things get a little more interesting.  It's a good thing school's almost out, because the four girls have a wild summer in store for them.

Mari and her gang of misfits innocently upload a photo of a funny-looking dog they find at the local Animal Shelter.  Turns out they've blown the cover of an alien who's hiding from a race of bloodthirsty fiends.

To complicate things, their dusty desert town is next to one of the fabled U.S. National Laboratories.   In the depths of this high-tech, high-security compound lies something left by a long-vanished race known as the Eldest.  No one knows what it does or how it works- well, no one human- but everyone wants to get their hands on it.

And so begins the battle for Earth.  Take one fleet of invading monsters, throw in some sleazy cable TV shows, kidnappings,  burning houses, and Native American ceremonies, stir well and bring to a boil, and you've got the recipe for a massively entertaining read.  Part coming-of-age story, part alien invasion tale, Killer Aliens Vs. Badass Teens! is, In turn, touching, funny, romantic, and mind-boggling.
