@CMB5594 The book centers on Frannie Devin O'Neil, a veterinarian, whose husband was killed three years before the story takes place. The action takes place in Bear Bluff Colorado. She meets Kit Harrison, an FBI agent, when he rents a cabin in the woods behind her house. One night after a friend's mysterious death, Frannie sees a mysterious girl with wings running through the forest. The girl's name is Max and she and her flock have escaped from the school. The girl and the flock ask Kit and the FBI for help...so on and so forth. It's basically a spin-off of the Maximum Ride Series. Seems kind of like a retelling in my opinion. I hope this helped.
