When students of St Ignatius go missing, painter and amateur sleuth Georgia O'Keeffe must infiltrate the school to figure out what's going on in this thrilling historical mystery set in 1930s New Mexico from multi award-winning author Kathryn Lasky.

New Mexico, 1936. Settling in for a harsh winter alone at her house at the Ghost Ranch, painter and occasional amateur sleuth Georgia O'Keeffe makes the most of the weather before a storm rolls in. But when she finds the ideal spot to capture a particularly nice sunset, Georgia discovers a boy—cold, exhausted, and desperate . . .

Joseph Reyes is a student at St Ignatius School, and he claims that sinister Sister Angelica and Father Raphael have raped and killed his sister. And she is not the only one who suddenly went missing!

Georgia is determined to find out what's happening at this seemingly peculiar school, but as she investigates she uncovers even more disturbing machinations that link the school to the newly founded Opus Dei institution and its cult-like practices as well as Nazis and hidden spies—not knowing how much she puts herself in danger.
