Is the story plot or character driven? The plot is rather straightforward despite the time travel options so I would say this story is character driven.
Who in this book would you most like to meet? I would like to meet Yvaine. She's very witty and she would be hilarious.
Do any characters grow or change during the course of the novel? Charlie certainly changes a lot in how, he sees things. Yvaine develops a strong attachment to Charlie. Fink let's go of his rules and regulations to help his son.
What motivates a given character’s actions? The kids were thieves. They stole in order to eat and have a place to stay. We all would try to do whatever it takes to survive.
Disclosure: I received a review copy of this book from the author.
