One word that describes a character. Survivor - He found, guns, ammo, first aid supplies, dogs. And he parked a UPS truck in front of his house to block the entrance.
Compare two of the characters in this book. Mary - Wife, mother and teacher. Laura - Pretty 22 year old college student.
Rewrite the ending of the book. I would have it jump 12 years and give Annah a young man in her life.
Disclosure: I received a review copy of this book from the author.
