This was my Amazon Prime borrow for June. I was a little worried - I have an old fashioned Kindle without even a touch screen, and thought navigating this "choose your won adventure" book might drive me crazy. It was actually easy and worked well.
It was a fun little book. It had enough references to the original book it is based on (Fatal Shadows) but with lots of new twists and turns including a lovely illustration. :-) Borrowing it was the right choice though - I don't see going through all the branches of the story more than once or twice.
