This is a really interesting idea for a story. Also, the setting and culture added to book's intrigue.
The ending was unexpected - it wasn't all about her.
David Pittu seemed to have a slight accent I thought, and that helped make me feel the culture of the country it was set in.
Ishigami was a pretty deep guy.
A book I am still thinking about a week after finishing--is certainly worth 5-stars in my rating system. This book has a brainy plot that slowly and methodically reveals the depth of "devotion."
This is a how-it-was-done rather than a whodunnit that really keeps your attention. Excellent plot and writing. I recommend it to all.
I enjoyed to twists and turns of the story. I thought I knew what happened, but in the end, I found out more.
