Edge of my seat....

I really love these books with Emma. Her creative way of solving crimes is so interesting. And there's a lot to follow but its written in a way that is easy to read and understand. After all the books with her, she becomes a familiar person that I will miss if this series ends. So intriguing and enlightening, she along with her chosen family are a part of my life.

Emma is amazing

Emma Griffin is a force to be reckoned with. She has such a sharp mind that she can do as much as a whole team. And this time she follows the tracks of cyber bullies who were becoming victims themselves. But why? Don't worry Emma can figure it out. And hopefully in the next book she'll take care of Doe.

In this story Emma sees the negative impact of social media on adolescents and how it can harm mental health and families. Not only is this story about social exclusion but also online bullying and psychological torture. It's an interesting although unexpected ending to this case (for me). I'm interested in the next book to learn more about Doe's life.

The girl on thecOutside(Emma Griffin FBI Mystery Book 41)

OMG!!!!!!!!! This book was so crazy, I didn't really know who the murderer was until the very end. Emma and her team did an amazing job catching the killer and preventing more murders. I would love to be like Emma and be able to solve these crimes. I can't wait for the next case.

Teenagers are being killed one by one in what appears to be revenge for them surviving a car crash. FBI Agent Emma Griffin is called in to solve the case. This one is twisty and full of surprises that will leave you guessing all the way up to the end! Don't miss this one!

Emma always has my head spinning

As usual, Emma has my head spinning! The way she thinks is astounding. Love that she gets help from Xavier again. The sourdough stories are hilarious! Don’t want her stories to ever end!

A must read

From start to finish this book had me at the edge of my seat. I can always count on Emma to solve the case even though I still don't know how she does it. Hooray A J Rivers you did it again.

This was an excellent story about Emma looking who killed some young girls and why and with her excellent skills and mind finds who done it with lots of suspense and drama and action. Thank you for this awesome story.

The mystery in this book was good but the expectation was it would be about “Doe” and Doe appeared only at the beginning and end of the book. Seems must continue on to next book to again catch up with Doe. If that had not been the expectation, would have rated this book a 4.

I always enjoy this series but i was disappointed. I thought it was very convoluted and not something the reader could really follow. Also I expected there to be more about Doe. I am starting the next book and hope it lives up to my expectations

my heart is beating so fast

Everything is coming together and my heart is beating so fast for everything going on with Doe. The rest of the story was just as appealing and kept my heart racing and the ending I literally DID NOT SEE COMING! Can’t wait to jump into the next book.

Doe?

Disappointed that Doe wasn’t found or even looked for after Emma got there because she was missing. It’s like she was forgotten and put on the back burner for another time.

boring

Too much explaining and rambling on. It makes so bored I just want to put the book down. Unfortunately the last few books in the series have been like this.

Another good one

I’ve read and (more or less) liked them all. I’m ready to find out who Doe is though. Come on Rivers!!!
