Goodreads Synopsis:

A device that can save a life is also one that can end it

Kadence, a new type of implanted defibrillator, misfires in a patient visiting University Hospital for a routine medical procedure—causing the heart rhythm problem it’s meant to correct. Dr. Kate Downey, an experienced anesthesiologist, resuscitates the patient, but she grows concerned for a loved one who recently received the same device—her beloved Great-Aunt Irm.

When a second device misfires, Kate turns to Nikki Yarborough, her friend and Aunt Irm’s cardiologist. Though Nikki helps protect Kate’s aunt, she is prevented from alerting other patients by the corporate greed of her department chairman. As the inventor of the device and part owner of MDI, the company he formed to commercialize it, he claims that the device misfires are due to a soon-to-be-corrected software bug. Kate learns his claim is false.

The misfires continue as Christian O’Donnell, a friend and lawyer, comes to town to facilitate the sale of MDI. Kate and Nikki are drawn into a race to find the source of the malfunctions, but threats to Nikki and a mysterious murder complicate their progress. Are the seemingly random shocks misfires, or are they attacks?

A jaw-dropping twist causes her to rethink everything she once thought she knew, but Kate will stop at nothing to protect her aunt and the other patients whose life-saving devices could turn on them at any moment.


First Line:

You aren’t gonna let me die this time, are ya, Doc? Oh boy.

Misfire by Tammy Euliano

As I stated in my review of Fatal Intent, I do not read/review medical thrillers. But after reading these two books, I realize I will have to fix that. Like Fatal Intent, Misfire was an excellent read that kept me glued to the book.

There are trigger warnings in Misfire. There are scenes of gore at several points in the book. There is a scene where Kate does CPR on her aunt. There are scenes at the end of the book that broke me. If you want to know what, use the contact me page and ask what they were. Because of spoilers, I won’t include it in the review. I will mention it, but I won’t come right out and say what.

Misfire is a fast-paced book that takes place shortly after the events of Fatal Intent. Kate is still dealing with what Adam did, which included trying to kill her great-aunt Irma, Christian (her lawyer), and killing her husband (and his brother), Greg. Her great-aunt was dealt a more severe blow during that attack, suffering a heart attack and needing a pacemaker installed. Kate noticed that people with Kadence installed were suffering from an elevated rate of heart attacks and disruptions. But, when Irma suffers an attack after a routine visit with her cardiologist, Kate starts digging into the study. What she finds stuns her and also sets off a chain of events which outcomes she didn’t see coming. What happened? Why is Kadence misfiring? Who is behind it?

The characters in Misfire were as wonderfully detailed as they were in Fatal Intent. I liked that they still appeared realistic and made me get invested in their lives.

  • Kate—She was still that great person from Fatal Intent. I liked that she wanted to move forward (and was urged to by Aunt Irma) but was hesitant. She regrets being distant from her friends (like when she helped with Ronnie’s pregnancy). I believe she was so stuck on helping Nikki and Ian because of that. As with the last book, she didn’t want to get sucked into the drama with Kadence. She was moved to action when her aunt was harmed by it and when multiple people died in a horrific accident caused when a Kadence misfired when someone was driving. Her solid moral character demanded that she look into it and discover why it was happening. I don’t think she expected to find out what she found out.

The secondary characters did add extra depth to the book. I loved the extra attention paid to Aunt Irma and Christian in this book. Christian’s secondary storyline broke my heart, and the resolution had me sobbing on the couch. The only character I didn’t care for from the beginning was Nikki. There was something about her that rubbed me the wrong way.

Misfire fits perfectly into the medical thriller and mystery genre. The author had a little spark of romance in there too. The mystery angle of the book was terrific. A twist in the storyline at the end stunned me and made me sick.

The storyline with Aunt Irma, Kate, Christian, and the search for Nikki was well written. I loved how the author took me for a ride with this storyline. I learned more about pacemakers in this book than I would have known about, ever. But that is what made this storyline so good. It was realistic. Also, I couldn’t get over the twist at the end of this storyline. It was maddening, heartbreaking, and just evil.

The storyline with Nikki, Kate, the Kadence device, and Dr. Cantrell was interesting. Interesting because I could see people like Dr. Cantrell doing what he did in the book. Sure, he was not a nice guy who didn’t do the right thing. But, in the end, he did redeem himself a little bit, in his eyes. I wouldn’t say I liked how he treated Nikki and Kate, even with the credible evidence that Kate had about Kadence.

The end of Misfire was equally thrilling and sad. I did not see the twist coming (as I stated above), and it took me by surprise. The author was able to wrap up all the other storylines in a way that satisfied me as a reader. I also cannot wait to read more books in this series.

I would recommend Misfire to anyone over 21. There is graphic violence, mild language, and no sex.
