Michael Buckley 
National Espionage, Rescue, and Defense Society (NERDS Book One) [EPUB ebook] 

NERDS combines all the excitement of international espionage with all the awkwardness of elementary school, and the results are hilarious. A group of unpopular fifth graders run a spy network from inside their school. With the help of cutting-edge science, they transform their nerdy qualities into incredible abilities! Their enemies? An array of James Bond-style villains, each with an evil plan more diabolical and more ridiculous than the last. Publishers Weekly raved: "Buckley has a flair for exaggerated humor." School Library Journal said: "Funny, clever, and thoroughly entertaining."
