Are you a teen aged 12 to 19 who has read this book or wants to? Sign up to join the discussion. This discussion is led by Ms. Larissa, of the Tin Can Mailman Bookstore, and will meet in person at Arcata Library. An action-packed plot tracks a vendetta against a war-torn world.

A frontier girl named Zetian rejects gender roles and upends patriarchy with fierce feminism.
