Watch The Shadows by Robin Winter

Watch The Shadows - Robin Winter
Hmmm.
For the first ninety-something pages, I was utterly and completely bored. I even actually contemplated DNF'ing the book. Then it picked up and started to get good, for most of the last half, anyway. I was excited reading about these alien things going around killing people and animals. It was intriguing to learn about them and wait for them to strike again. It was a totally new way of portraying alien species in stories, and I appreciated the ingenuity.
I hated, yes, hated, the very end. Literally, it was the last two pages. Not how I wanted it to end off the story at all. It went back to total boredom, so quick. Out of 174 pages, only about 70 of them were any good.
