Secrets of Hopelight

I read Secrets of Hopelight. I got this book from netgalley. I liked this book, except for the ending.
Spoiler alert:
It doesn't say what happened to her mom or Desmond or the other ones that were unchipped. And it doesn't mention how Desmond got caught and they got away. I feel like the book was not complete. And that's why I only gave the book 4 stars.
