Kids should find this ninja detective story entertaining enough, but it felt shallow compared to similar Southern mystery "Three Time Lucky" by Turnage. The characters lacked depth, with Randi's family history making her somewhat of an exception. I felt like the breaking-and-entering and ninja sequences were too unbelievable and not at all explored for the serious events they would be in real life. It's a quick read, though, and the mystery itself was pretty interesting. 
 I received this eARC from the publisher via edelweiss.
