Helpful Score: 4
This book was just as good as the first one. Cassiel is a smart, tough and flawed heroine. Her desire to save humanity instead of destroying it felt genuine. Her emerging romance with Luis was just the right touch; it wasn't the main focus of the story, but simmered nicely in the background. There was plenty of action and suspense to keep me on the edge of my seat and I anxiously await the next installment.
