On their honeymoon, they finally have some downtime together-when a call comes in for an urgent case: women are being strangled at a rapid rate in the D.C. area by what appears to be a serial killer.

Ça fait longtemps Mackenzie N’est ce pas ??
Encore une fois je regrette plus mon attachement incroyable à cette série ♥️
Trois filles retrouvées dans des appartements assassinées ligotées et nuées ! Un tableau mystérieux !

Pas de signe ! Pas d’indice ! Pas de pistes !

Un fils les réunissent toutes ses domaines d’études universitaires : La Politique.
Et leurs présences à des événements spéciaux et puis des connaissances en commun mystérieuses et floues.

Une aventure fiévreuse et pleine de tension et de stress à part le suspense absolu bien sûr !

Et une fin choquante et un tueur hors paire !!!

La spécificité de ce tome et pourquoi la tension est augmentée au fils des événements Mackenzie est enceinte de 16 semaines et encore active sur le terrain elle a caché sa grossesse pour continuer l’enquête mais même après son annonce elle n’a pas pu de s’éloigner de toute l’affaire avant sa résolution, un tome hyper stressant , j’avais vraiment peur qu’elle perds son fœtus mais heureusement une fin satisfaisante !

This was an interesting book for Mackenzie, so many changes in her life, most of them she really embraced, a couple not so much. I loved how excited both she and Ellington are for the baby, but worried that she hadn't talked to her boss about being pregnant. I really worried something bad would happen during the case. It did, but it happened in a way that really made Mackenzie aware of how much the baby meant to her, even going so far as to changing her behavior, a big thing for her.

I loved the choice that Mackenzie and Ellington made at the start of the book, it was perfect for them and allowed them to concentrate on what was important to them, their relationship.

I was a bit stunned on who the bad guy ended up being, how he let everyone see the monster in him and how he was caught. What he did at the end was such a cowards choice.

It will be interesting to see how Mackenzie handles the changes she is having forced upon her at work. I'm sure she will still find a way to be active in cases.

These books are incredibly addictive and as you can see from my reading list, I am reading them at the rate of knots. I have been devouring this series and every other series this author has written. What I will note, is that the books seem to be getting shorter at the same price point and the editing leaves a lot to be desired. However, the stories just bring me back for more and more and more.

This one is just as good as all the ones that came before in the series and as every other book by this author. However I am deducting one star for "in need of editing."

This author has definitely found the formula for a good story. I especially like the growth of Mackenzie White as the series progresses. But please PLEASE get an editor! This book (and others) has had him and her used for the same person in one sentence. There is the old That for Than and much more. It does eventually detract from the reading as you try to figure out what is meant.

These books are not Kindle Unlimited, you have to buy each one and the price goes up as the series progresses. So you get the first in the series for free. By the fifth one you are paying $6.99 per book. I did that for a while and then got smart and borrowed the Kindle digital version from the library. All I am saying is GET AN EDITOR! PLEASE!

Okay, now that my rant is over, I will again say this is just as exciting, just as addicting as the books that came before in this series and all the other series written by this author. I can't get enough. But I am no longer paying $7 for a two day read. And I do expect the books to be edited.

Gripping

Considering that this is an almost end of the series, (I like to read from the first book) this book shows how Mackenzie White mind works for the cases she has with the FBI. This could be a stand alone book. Well written. I highly recommend the book.

I was given an advanced copy for review and I was in no way compensated other than reading another success by Mr. Pierce.

MacKenzie and Ellington are on their honeymoon in Iceland when they get called in by McGraft for a case. Someone is killing young college girls, the killer is evolving and each killing is a little worse than the last. Mac and Ellington need to solve this fast before anyone else dies, so they pull out all the stops. During the course of the investigation Mac is attacked and barely escapes with her life and oh yes...Mac is pregnant and fighting morning sickness.

One of the things I like about this young writer is his proliferation. Yes, I read one review about predictability, another about editing and another about sappiness! But I don't see any of that as a negative. Mr. Pierce draws you in and makes you feel like you have know these characters all your life and you never have to wait six months to a year for another story. For me as a reader, I value that as much as a good story.

Mackenzie is still hiding something from her boss. This time it's extremely selfish and stupid. Needless to say this book showed me how stupid she is. I don't know if I will continue the series. I was glad that her boss finally grew a pair. She should have been fired many times over.





Spoiler: The author does realize 16-17 weeks isn't the beginning of pregnancy right.... She's half way there.

This book was good. I was very curious to see how they would end it because Mackenzie usually gets in some kind of fight at the end of the books but this time she was pregnant. The book turned out really good. I felt like I was watching an SVU episode. Giving vibes of the og series. We even got some Ellington povs.

I just finished reading it. I really enjoyed reading this book because we got to see a different side of Mackenzie. We saw struggle with her every decision when it came to motherhood and her career. It felt very relatable. I can’t wait to read the next one!

The writer repeated themselves nearly verbatim multiple times during the beginning of the book. Overall the story is still interesting enough that I can’t seem to stop reading the series but I will say I’m ready for it to be over.

Shockingly a very, very good read. I prefer Riley Paige and the newest, Kate Wise, but I found Mac White to be a great character.

Confusing

I love this series, but this book had too many suspects to keep track of. I hope the next book in the series is as exciting as it sounds.
