This book is somewhat of a hybrid, classic David Weber military SF for the first half of the book and then picks up a fantasy (horror?) theme in the second half of the book with the introduction of a being from greek mythology and possession of the main character. The action is fast and furious throughout the first half of the story as we see Alicia Devries reach her full potential in the military. I was at first a little confused regarding the direction of the story with the introduction of the Fury character but I kept reading and it really finished with a bang. I would recommend this book to anyone who has enjoyed the Honor Harrington novels.
