Aidan and Brianna Rose's story. He has not helped an Innocent in sixty six years until he hears Brianna's scream of terror across centuries and leaps to modern day Manhattan to rescue her from subs. The reader has to go through the reason he decided to stop saving Innocents, his grief, his hatred, and resistance. I liked this book but preferred the 2nd and 3rd in the Rose series. To me the story seemed to drag on a bit and had a small dose of action and adventure.
