Is the story plot or character driven? A little bit of both. The plot is strong and there are two strong main characters that drive the story.
Is the plot well-developed? Yes, by the time you get to the end, all angles of the story have been covered and the author ties up all loose ends.
Who in this book would you most like to meet? Niki of course. In some ways, she reminds me of Kate Beckett from Castle. Bold, brave and rash at the same time.
Disclosure: I received a review copy of this book from the author.
