In this story inspired by Jules Verne's "20,000 Leagues Under the Sea," Ana Dakkar, a freshman at Harding-Pencroft Academy, a five-year high school that graduates the best marine scientists, naval warriors, navigators, and underwater explorers in the world, makes astounding discoveries about her heritage and puts her leadership skills to the test against deadly enemies from a rival school.

Thirteen-year-old Piper Davis records in her diary her experiences beginning in December 1941 when her brother joins the Navy, the United States goes to war, she attempts to document her life through photography, and her father--the pastor for a Japanese Baptist Church in Seattle--follows his congregants to an Idaho internment camp, taking her along with him. Includes historical notes.
