What would the main character be likely to do if s/he visited? Katie would talk and remind us to tell our children to never be alone. To not allow them to walk down to the store, ride their bike or anything by themselves. She would tell us how important it is to protect our little ones.
At the end of the book, do you feel hope for the characters? Only hope I feel is that readers will not know who kidnapped Katie. We are left to wonder who did this.
What makes a minor character memorable? How they help the main character during troubling times. Avery is the perfect example. He was helpful and even went so far as to provide Katie a book so she could learn more about investigations.
Disclosure: I received a review copy of this book from the author.
