The stakes are higher in this book with Raiden on the move, not only to take what he wants but to destroy what he doesn't need. And Audra's mother is back in a secondary role causing a little potential mayhem of her own.
It's easy to drop the tension in a second book in a series, or to introduce so many new characters and plot twists that the reader becomes confused. But Messenger does not fall into any of these traps. She has created a compelling and engaging story that rounds off nicely, but still leaves us needing to find out what happens next. When's the third book coming out????
