Instead, she finds herself delving into the dark secrets of the world, mastering magic, finding allies, and uncovering a vast conspiracy. However, just because the time loop can save her life doesn’t mean it can save her from everything. Mirian must navigate a dangerous world changed by the magitech revolution.
