Gr 59 Take flight with this comprehensive overview of different types of aircraft, from drones to gliders to space planes. The books are full of real-life examples of how these machines are used, as well as a rundown of their history and development. The layouts include strong graphics, with full-page photographs of the aircraft in motion along with fun facts. The text, which is written at a fourth grade reading level, features one brief paragraph per page. This series is on the longer side for hi-lo nonfiction, and while the books are extremely detailed and full of information, they may hold less appeal to striving readers outside of true aviation enthusiasts. The end features an "Xtreme Challenge" with several comprehension questions for readers, as well as a QR code linking to additional online resources. VERDICT While the audience may be limited, this series is full of detailed aircraft content and is best suited to striving readers at the secondary level.
