Spy School, by Stuart Gibbs, is a really good, light, and easy read. The book's main attraction is its plot twists. The unknown double agent, hidden 'spy' school, and secret organization all combine to make a great action-packed, half-romance novel. The ending also gets the reader hyped up for the next book in the series. Stuart Gibbs uses great foreshadowing throughout the book, and hints at every little detail in the plot. Although the plot is sort-of cliche and some characters are kind-of bland, the book sums up to be a highly entertaining read. I would recommend this book to anyone willing to put in the little time it takes to read it.
