Just loved reading this book. I always enjoy reading books set in the Philadelphia area because the landmarks and settings are so familiar to me. But this book really took me by surprise. I can't include in this review what I liked best about the book because I think it would spoil it for others!

This was not what I was expecting, but I loved it. A man infiltrates himself into a school with a mission in mind.

This is small, but did anyone else notice that in the jacket description it talks about “Justin” Larkin but in the book it’s “Jordan”!? It really bothered me!

So I read this book in a day. Couldn't put it down. I've a lot of Lisa Scottoline's books, and I always enjoy them. This one is different, and it doesn't go in the direction I expected. I especially liked the interact with the high school kids. Wish there had been more there, but only had a few days to work.

As always, Lisa Scottoline wrote another terrific book! She had me from the very first page wondering what the plot was about. By the second part of the book I couldn't stop reading. Looking forward to her next book.

I’d give it about a 3.5. It was entertaining with a twist I didn’t expect.

Nice twist I did not see coming after that beginning (I think it was with Step 2).
A little over the top action-sequence in the end, and it was a little too neat after that, nearly bordering on hea (hope this does not count as a spoiler). For this and the lone-hero feeling 1 star less, could easily have been a 5star read.
A few times different POV, but all in all not too many and well done.
Sex mentioned but happening off page, although Sexting plays a certain role in the story.
The problems of the different families felt a bit much, but where all in all very real.
Main parts of the book read like one lone hero trying to save it all, hindered by having one chef with his own goals and playing it by the book.
Nice integration of current technology (Smartphones, surveillance App), I think no hacking or (luckily) even embellished/unrealistic use of technology.

Recommended, reasonably fast page-turner, no real thriller, though. Would have wished for a more bloody ending, with lots more casualties. Standalone, nicely finished. Will probably remember this author and try to read more of her, depending on theme.
