#BlogTour: A Killer Motive by Hannah Mary McKinnon

For this blog tour, we’re looking at a masterful thriller that will keep you on the edge of your seat. For this blog tour, we’re looking at A Killer Motive by Hannah Mary McKinnon.

First, the review I posted to the book sites (BookBub.com / BookHype.com / Goodreads.com / PageBound.co / TheStoryGraph.com) and YouTube:

Masterful Thriller That Will Keep You On The Edge Of Your Seat. McKinnon has become a true master of the kind of suspense/ thriller where you’re still on the edge of your seat and trying to figure out what comes next… when their suddenly is no more “next” to be had in the book.

Now, don’t get me wrong, she tells a complete story every time. She’s just also become a master of telling that story and then leaving *just* enough dangling *so* well that you want that story to continue, even though it has reached its final point for the story she was telling in this particular tale.

Arguably one “weakness” here – more something I’ve just never gotten into and don’t really understand the “appeal” of – is the podcast base of this tale. McKinnon uses it particularly well to tell her story, both in featuring actual podcasts within the tale and in using the relationships of the various personalities that create and work on and around podcasts to great effect.

For me though, the strength of this tale really is the relational. McKinnon creates here a woman with several crucial relationships… and one she isn’t aware of that is about to push her to her limits. Because the best relationship in this book isn’t the marriage or the friend or any of the other usual suspects.

It is the antagonist our leading lady finds out through this tale that she has. While our leading lady is no (Sherlock) Holmes or (Aloysious) Pendergast or (Charles) Xavier or even (Clarice) Starling, our antagonist here absolutely is one that fans of Moriarty or Diogenes or Lensherr or Lecter will absolutely love. Because yes, the antagonist McKinnon creates here *is* that good.

And yet… if our antagonist *is* that damn good and one way to measure someone is by the strength and ability of their enemies… doesn’t that mean that our leading lady actually *is* that damn good herself?

How about you read the book and write your own review on whatever platform you’re reading this review on and let us know. 🙂 Feel free to tag me in it, assuming that is possible on said platform.

Overall though, this book really is very well done, exactly as fans of McKinnon expect from her… and may even be her best yet.

Very much recommended.

Chapter 1
Stella

My pulse thudded in my neck like Morse code. A steady tap-tap loosely translating as come on. Shoving my hands under my thighs, I slid farther down the passenger seat and peered over the dashboard toward the darkened house at the end of the street.

For ten minutes I’d willed the motion-activated porch lights to stay off. Hoped the heavy living room drapes with the silver ring print I’d been mesmerized by as a kid would remain closed, allowing us to stay undetected.

Tap-tap.

Already 9:47 p.m. Where was he?

The cloudless Maine sky had long transitioned from bright blue to bubble gum pink before enveloping our corner of the East Coast in a blanket of rich black velvet. A cool breeze drifted through the open car window, providing a welcome break from the searing early August temperatures.

Rain was on its way for Portland and beyond tomorrow, which would be a welcome relief. For now, the sound of buzzing cicadas filled the Friday night air while this summer’s hottest anthem played on a radio somewhere in the distance.

The classic smell of freshly cut grass invaded my nostrils, conjuring memories of picnics in the park, running through sprinklers, and hands sticky from melting strawberry popsicles. Like those lazy days years ago, tonight would be perfect. All I needed was for my brother to show up.
“Do you think he changed his mind, Stella?” Jeff said, his voice a gentle rumble.

Glancing at my boyfriend, I took in his dark blond hair, straight nose, and the sculpted stubble accentuating a set of epic cheekbones. I let my gaze sweep across his toned biceps and chest. Underneath the faded-but-somehow-still-fitted Alanis Morissette T-shirt was a set of rock-hard abs I couldn’t wait to run my hands over again. Part of me almost wanted Max not to show up so we could go straight home.

I reached for Jeff’s hand and gave it a squeeze. “No, he’s too excited for the party. I bet he’s waiting for Mom and Dad to fall asleep in front of the TV.”
Jeff laughed. “Way to make them sound ancient.”

My parents were fifty-one. I was about to reply that compared to Jeff’s twenty-four years and my twenty-two, that was ancient, but the sight of Max emerging between a pair of fir trees stopped me. With a mischievous grin on his face, he speed-walked toward us, his hands tucked into the pockets of a Simpsons hoodie.
I smiled at my baby brother. Baby was slightly unfair considering his eighteenth birthday was under two weeks away, but I’d forever tease him about being four years younger. Max didn’t mind. He knew that from the moment I first saw him in the hospital, swaddled in a bunny-print blanket, his plump cheeks rosy red, I vowed I’d be the best big sister in the world.

Tonight, my solemn promise meant busting his grounded ass out of his minimum-security prison, aka our parents’ house, so he could join Jeff and me at what would be the coolest party of the weekend. Lighthouse Beach was a twenty-five-minute drive from Deering, the Portland neighborhood where Max and I had grown up, and now I couldn’t wait to get going.

Max slid into the back seat of Jeff’s old red pickup truck. I turned around, laughing at my brother’s beaming face and the perpetual impish twinkle in his green eyes, which looked so much like mine.

“We were about to leave,” I deadpanned. “Thought you’d chickened out.”

Max snorted. “As if.”

“Are we picking up Kenji?”

“He’s at his girlfriend’s so he’ll meet us at the beach,” Max said, before jokingly adding, “He’d better, considering he’s taking off next week. Some best friend he is, leaving me behind.”

“Hey,” I shot back with mock indignation. “I thought I was your best friend.”

“Are you two sure about this aiding and abetting?” Jeff cut in before Max could throw a good-natured sibling zinger my way. “Your mom will go ballistic if she finds out.”

Max shrugged. “I don’t care. She’s way overprotective.”

“You know her reasons,” Jeff said.

We all did. Mom’s older brother died when she was nine and he was seventeen. It was terrible how some asshole truck driver had run over our uncle, killing him instantly. Still, Max’s rebellion tonight was fueled by the fact Mom had banned him from going to California with Kenji, saying it was too far away, and Max was too young. They’d had a massive argument about it, which led to my brother being grounded for the weekend, hence tonight’s great escape.

“I told them I was heading to bed,” Max said. “They never check, but I stacked my pillows under the duvet just in case. Nobody will notice.”

“If they do, I’ll take the full blame.” I patted Jeff’s hand. “Max, we’ll drive you home. No after-parties with Kenji, got it? What Mom and Dad don’t know can’t hurt them.”

“Sir, yes, sir.” Max gave me a salute. “Anyway, I’ll need some sleep. I’m volunteering at the clinic tomorrow. Woolly had a mass removed and I want to be there for him.”

“Woolly?” Jeff said. “Dog or sheep?”

My brother grinned. “Giant Angora rabbit. He’s awesome.”

“You’re such a softie,” I said before letting out a whoop. “All right, let’s go. Lighthouse Beach, here we come.”

Book Description:
In this thriller for fans of Ashley Elston and Jeneva Rose, a manipulative kidnapper gives a true crime podcaster one week to locate her brother’s best friend. If she succeeds, she’ll learn the truth about her brother’s disappearance six years ago, but if she fails, his friend will die.
You never know who’s listening.

To Stella Dixon, sneaking her teenage brother out of their parents’ house for a beach party was harmless fun—until Max disappeared without a trace.
Six years later, Stella’s family is still broken, and she can’t let go of her guilt. The only thing that keeps her going is helping other families find closure through A Killer Motive, her true crime podcast.

In a bid to find new sponsors and keep making episodes, Stella goes on a local radio show. But when she says on air that if she had just one clue, she’d find Max and bring whoever hurt him to justice, someone takes it as a challenge.

A mysterious invitation to play a game arrives, with the promise that if Stella wins, she’ll get information about what happened to Max. Stella thinks it’s a sick joke…until Max’s best friend vanishes. And she’s given new instructions: tell nobody or people will die.

Desperate and unable to trust anyone, Stella agrees. But beating a twisted, invisible enemy seems impossible when they make all the rules…
