It’s time to pay the exterminator.

After barely surviving the ghosts of her past, Special Agent Emma Last is desperate to move forward. But just as she starts to believe she can leave it all behind, her colleague makes a shocking claim.

She saw Emma in the afterlife. And she wants answers.

Now, Emma’s sanity is at question, and she fears her career may be on the line.

But any questions about what really happened during her last case are put on hold when a mutilated body is found—a tattoo cut from his skin. Emma and her team suspect gang activity. Until they find a dead cockroach stuffed in his pocket, and a sinister email is directed to the police.

“Cockroaches overrun our city…and someone needs to do the cleaning.”

When a second victim appears, it’s clear this isn’t a turf war—it’s a vigilante’s hunt. A predator collecting trophies. And now, Emma is the ultimate prize.

Last Sign is the gripping thirteenth book in the Emma Last series by bestselling author Mary Stone, where the most dangerous infestations don’t crawl in the shadows—they walk among us.

LAST SIGN is the thirteenth Installment in Mary Stone's Emma Last FBI Mystery Series. If you are new to the series, you'll discover each investigation and each bad character is unique and the stories are page turners keeping you on the edge of your seat. Let's not forget the occasional ghost helping or hindering the investigations.

Denae reveals what she remembers as she was dying forcing Emma to reveal her  ability to see ghosts and the 'Other'.  Vance is back after his injuries and sure he's being pranked and not happy about it. The team is tense, but hopefully their new case will bring them together. Someone is killing gang members and dumping them near the law enforcement offices. In a gun fight with the killer, Vance dissapears. Everyone is trying to find the killer and discover what happened to Vance before he becomes a victim. 

This is another well written story with plenty of suspense, twists and turns. I received a copy of this book from the author and the above is my honest review. I also recommend this book and the entire Emma Last FBI series to those that enjoy thrillers.

Emma Last just came off of a very tough case. And now she is being questioned about her abilities to communicate with ghosts! Leo and Mia are on board as they have witnessed the shocking results of their last case. However, convincing the Supervisory Special Agent in charge and their last team member is another story. Just as they are getting into the discussion they are pulled into another brutal murder. Someone is killing gang members at random in a brutal way and cutting their tattoos from their bodies. In a shootout with the perpetrator Vance is kidnapped. Worse there is heavy fire coming from an unknown source. Who is the new shooter. Emma thinks this may be related to the case in Salem, but she can't be sure. There is a clue early on, but you might miss it. Lots of turns in this book. Good characters and good story.

When Denae speaks to SSA Jacinda Hollingsworth about Emma appearing to her and calling out to her as she was dying. When Emma is questioned about this, she has to reveal her secret about her ability to see ghosts and speak with them. Jacinda is willing to keep an open mind but Vance totally does not believe this and constantly is ridiculing Emma. Then they receive a new case where someone seems to be murdering members from various gangs, removing their gang tattoo, putting a dead cockroach in a pocket, and leaving the bodies at police/FBI headquarters, then finally one is left at Emma's doorstep, and it becomes personal when she realizes that her supposedly "sister" is involved with these murders. It is a turn pager and leaves you wanting the next book QUICKLY!!

Special Agent Emma Last is a very intriguing character. Her ability to communicate with ghosts is an erie and complex gift. This fast paced story has a vigilante killer targeting gang members. What a well written story Mary Stone has created. Along with working at solving this case Emma has to contend with the fallout after SA Vance Jessup hears about her ghostly talent. He laughs and ridicules her continuously. Luckily “the other” inhabitants continue to give Emma clues allowing her to solve the case and rescue a kidnapped Vance. One of the author’s best in the Emma Last series…and wait for the ending!!!

Young kid has found a way to make a lot of money, he delivers a packet of coke and gets a big wad of cash. He is expected to go right to the dealer to hand over the proceeds. He decides to make a quick stop at the home he shares with his sister and skim off some cash for them to use. What harm is there in that? Just prior to getting home he meets a stranger and bad things happen. When his body is found, Emma and team are called to investigate. This body has a slice of skin removed, suspected to have been a tattoo. This sets off additional murders and lots of research to find the answers. Fast paced, terrific read.

Emma has to face up with Ja in da and Vance about ghosts. It’s so hard on all of them. In the mean while the new vigilante starts to kill gang members in a gruesome way and finds a stranger helping him. It gets personal and hit with a lot of turns and cliff hanger at the end. This is the best of Ema Last series. I could not go into the details without spoilers. Again Bravo Mary and thank you for keeping us busy with the exciting thriller stories.

While Emma has started to brief Jacienda & Vance about what actually happened in Salem they get the word to assist the local police in a murder. An Unsub has killed a gang member and left him close to a police station with a message about eliminating “cockroaches” since they can’t or won’t do it. It later becomes personal for Emma as it looks like their also after her - to kill her

Vigilante Justice?

Another page turner, I couldn’t put it down. Emma and her FBI team are really put to the test this time. A vigilante is out to rid the streets of gang members blaming law enforcement for not keeping them safe. Hold on to your hats this is a stressful one.

This is the thirteenth book in the Emma Last FBI series. Someone is brutally killing gang members. Emma and her team are on the case. A lot of this book, though, is about Emma’s ability to communicate with ghosts and the problems that issue causes her. Another great addition to the series.

Great book

This series of Emma Last and her ghosts has been interesting. The team learning of her abilities has been crazy and a little of putting to some. I vigilante targeting gang members they have their job cut out for them. Especially when one of there own is taken.

Another edge of the seat page turner. I'm always so disappointed when I'm done because it means I have to wait for the next one. Vigilante vs. gang members. Emma Last vs. A mystery woman. And a team member questioning everyone's sanity.

A lot of action pitting the FBI against vigilantes.

A decent amount of action pitting the MPD and the FBI against vigilantes that are killing drug dealers and cutting off their tatoos.

lots of baggage - emotional, criminal, relarionship

This installment is both creepy and sad.

Emma’s secret is out - but not everyone is on board with the disclosure, and one of the team is kidnapped.

It’s become clear that Emma’s a target.
