This novel was not only intriguing; with a nice blend of science and fantasy, The Sailor Cipher would interest most of those looking for a technologically-based story with a hint of suspense. When Sailor York returns for her second year of studies at the prestigious school, she expects a year-long adventure filled with excitement and wonder - certainly not a missing big sister. As she uncovers more about the details concerning her sibling's possible kidnapping, Sailor finds herself caught in the middle of a dangerous game filled with rival factions. And her external struggles are only compounded by her own story: Sailor has a secret that she does not want to release, yet may have to in order to succeed in her missions. As a person who is always taken aback by the sheer progression of technology in the modern world, I enjoyed reading about the various new inventions and vehicles this book displayed. As being heavily based upon the work of actual National Geographic Society members, this series debut expertly pays homage to the organization's projects. The chapters are also well-organized, with each subplot complementing the others in their advancement. While the humor seems a little forced at times, this novel overall is a read you do not want to miss. I am definitely excited for the release of the next book in the series!
