Into the Night(Olivia Knight FBI Mystery Thriller Book 11)
OMG!!!!!!!!!! This book was amazing, it was also very sad. Three teenagers died, but because of that a prolific serial killer was caught. I didn't see how many people he killed, but he was murdering people for 24 years. He became a sadist killer, he decided that he had to add his own "artist flare" to his most recent murders, by carving up the bodies. I can't wait to read the next book. I do hope that in future books, I can learn about how FBI agents and other people who deal with the most horrible things that people can do to other people, learn to deal with what they see.

A definite must read book and series!
This has been an incredible series, and the stories just keep getting better and better. This story was heartbreaking in so many ways, as the death of a child is almost impossible to comprehend. It's made even worse by the horrific nature of the murder. There were many unexpected twists in the story, but as usual this dynamic duo always seems to see beyond the obvious. It's a fantastic series, and one that you certainly won't want to miss!
I would definitely recommend this book, series, and exceptional author.

Children who just want love and find being weird brings its own attention and quiet psychotic killers live in their twisted worlds ,while participating as professionals in acceptable friends and neighbors. A story that makes us insightful and open to living a better way. Great characters who overcome.

It was ok. Not the best but not the worst
I'm really just no longer liking the Olivia Knight character. I don't know if ill continue on in the series or not. This book had some good story line and it was a decent read but there is just something about the character that I no longer like. I've said that about a previous book and to me her character just isn't very likeable. I doubt it will change in any future books.

Great mystery and suspense
Another great book by The Grays! After a harrowing time on the island in the last book, to one where children are killed, has both Olivia and Brock thinking and talking about their own lives. This is such a good book and the investigation, never got close to the killertill the end. I love this series and the others written by the Grays. Need a good suspenseful mystery, the Grays have it all. Looking forward to the next book.

Was I supposed to read another book prior to reading this one? I feel really dumb but I don’t understand anything regarding the “island” and whoever Yaya was and all of that. Once I got into the actual storyline of the book I did enjoy it but I do not for the life of me understand what that other storyline was about. The main story was well done and I would probably read another book by this author

Elle and KS Gray did it again!
OLIVIA was never my favorite of the Gray series. She had always seemed a little whinging to me. Wow, this book is a sensitive and strong agent who is able to work a horrific case and be supportive to her partner who is clearly reeling from current events. Nothing like serial killers and butchered victims to take your mind off things!

A Very Riveting Book!!
This was a fast paced book that kept me on the edge of my seat. So much jaw dropping suspense had me glued to this book trying to figure out who the murderer was. So many twists and turns made it impossible to know for sure because it looked like one person and then another until the very end. The ending was explosive and unnerving. A great book!!

Always interesting!
Olivia and Brock always have interesting cases. Getting insight into the mind of serial killers is scary and interesting at the same time. I like the fact that you never figure out who the real villain is until the end. Great writing with the romance giving some relief to the horror of a serial killer.

Olivia and Brock are met with a killing that looks as though it could have a cult background. This case brings back some memories of a past case, and they begin to wonder who could actually be this cruel, especially to young teens.
Loving this series sooo much! The cases are fantastic, and the chemistry between Brock and Olivia is just perfect.

A change in pace brings you back to normal thoughts.
Another great read with a different pace and case to solve. Great characters and pace to keep Olivia and Brock back to the normal type of mystery. Gives you reason to look at your life and start to see the differences in your life and what's "normal" and what's not. Comparing your life and others around you.

Ok, creepy little Halloween town and the people. Glad that Olivia had Brock are back in the field. What a case to ease back into work, and add in family issues in the town and Olivia's hometown.
Ready for the next step.

Another great book!
Olivia and Brock are off to a new adventure after getting back from the island of the Game Master. This one was very interesting as Halloween was knocking on the door.

Loved the story. The growth of love between Brock and Olivia is beautiful in spite of the horrors they face . I wonder why they don’t invite Paxton to family gatherings.

Who Is Responsible?
Interesting story. While reading this book I tried to not picture the way the individuals were murdered. I didn't quest who the killer was until they were caught BoLivia and Brock. I felt sorry for the people who lost loved ones.

outstanding
The author draws you in and keeps your attention all through the novel. A serial killer is killing teenagers and leaving no clues. Couldn’t wait to find out who the killer was. Worth the read. Like the FBI agents, Olivia Knoght and Brock.
