Query: GOOD PACING AND PLOT

Shadow of a Doubt was well written with believable characters and circumstances. The main character, Kali, was a fully-formed human being. I'm old enough to remember the days before cell phones, so I found it fun to reminisce. I also thought that the relationships were authentic and the dialog natural. I liked this book and will probably want to read more from this author.
