Mixed feelings about this book
Format: Kindle
I do not recommend this to anyone suffering from trauma. There are some very triggering things in this book and it isn’t a justifiable risk for anyone who has PTSD.
However, if your life has been relatively “normal” and fairly mundane, then you might enjoy reading this book as an escape into a series of exciting events that put the characters through major suffering.
If books got ratings the way movies and TV shows do, I would rate it MA (mature audience) or R (restricted audience) for language, violence, sex, and thematic content. Reader discretion advised.
Pros- fast pace, twisty plot, mysteries, surprises, lots of action, hard to put down
Cons- often unrealistic portrayal of how real people would actually act in the various situations in the book, and sometimes the situations themselves felt a bit of a stretch
This was a plot-driven book with one-dimensional characters- “bad guys” predictably did and said horrible things, “good guys” reliably said and did “good” things. Nobody really surprised the reader, even when they did unexpected things, because it was more a matter of getting the full picture and then realizing that their actions were fully consistent with their place in the “good guy” or “bad guy” category.
Sometimes I found myself wondering if the author had any understanding of how trauma affects people. Those I know who suffer from PTSD or CPTSD don’t behave like the traumatized characters in this story. In many ways, it felt like a kind of wishful fantasy of how nice it would be if people who had been severely traumatized could recover in a relatively short time and in a straightforward way. Even taking some time to research how CPTSD and PTSD can affect trauma survivors could have helped the author write more realistic characters. They were overall too successful, healthy, and emotionally consistent, and said and did too many “right” things the “right” way. Conversely, when the perpetrators did things or said things, they were often too horrid and almost cartoonishly villainous.
There were a handful of ambiguous folks who defied being neatly categorized as “bad” or “good” but the central cast of characters were largely a flat and static bunch.
Nobody seemed to grow as a person or overcome any personal flaws, except for a couple of peripheral characters, and that growth happened largely off-page and was revealed at the end of the story rather than showcased as a central aspect of the book.
In terms of pacing and the twistiness of the plot itself, it was very fast-paced and intense. It was a creative story full of mysteries to solve. Many times I couldn’t pull myself away from reading it because I was so curious about how things would unfold and what was really going on.
Overall, I found it to be an interesting read, but the unconvincing way the characters behaved, in light of how real live people respond to trauma, kept taking me out of the story and making me occasionally roll my eyes or shake my head at the cluelessness of the portrayal of traumatized people.
It would require some spoilers to get more specific than that. If you don’t mind shallowly sketched characters who seem to be permanently locked into their “good guy” or “bad guy” identities, and you enjoy fast-paced thrillers with twisty plots and convoluted storylines, this one is worth your time. I wouldn’t recommend it to most of the people I personally know, though, for the reasons I mentioned.

A high stakes political agenda
Format: Kindle
Cami was about to embark on her college years with her boyfriend when she found out she was pregnant. Worse than that was when she arrived home and was ambushed by two men who had already tied up her mother and younger sister. Knowing nothing good could come from this ordeal Cami planned to escape her captivity.
…
Rex had been running when he saw police activity near Cami’s neighborhood. Concerned for her well-being he went to investigate. He shouldn’t have gotten involved because he became a suspect and now the community looks at him as a dangerous criminal eventhough he was cleared of any wrongdoing. The scholarship program that was supposed to be his escape from this community was revoked so he enlisted in the military.
…
Mia Sheridan certainly knows her way around a good emotional read. Trauma of this magnitude can only be explained by a seasoned writer. I appreciated this well thought out storyline. The writing was strong, yet I still found myself not completely invested. There were high points and low points where my interest would waver depending upon the content. This started off with an intense scene that I thought would carry over the entirety of the story. The story had a shift that disrupted the pace. I had to regroup my thoughts. The content was tragic and while I appreciated the concept I didn’t like the execution in certain places. There were many layers to this story that were kept from the reader to serve a purpose later on. Overall, The Fix was a book about survival and how women are capable of greatness.
…
The Fix offers a balance of tragedy with hope not pushing too much in either direction. The dark balances with the light carving the way towards a future filled with happiness.

Do overs
Format: Kindle
With every phenomenal book Mia reminds me why I became an obsessed reader. Her stories are what keep me up late into the night, unable to put them down or walk away. Rich in brimming emotions, thrumming with adrenaline rush at impending danger, this book will make you forget the world exists beyond its pages.
When your fave author writes a book, you don't peek at the Blurb or look for massive list of triggers. You cover your eyes and jump in.
This tragically profound story hits you with a force of a runaway juggernaut, drawing you in till you are completely consumed in the characters' lives. First few pages sweep you in like rushing tidal waves, one after another, pulling you under, in inescapable tsunami of emotions.
“Fair is a myth,” Rex said. “Nothing in this messed-up life is fair.”
I Landed straight into Camille Cortlandt's house where an unspeakable crime is in progress. Cami, her sister Elle and her mom are subjected to horrible torture and assault. Her father tied and assaulted too.
And she was worried about another smaller problem from her boyfriend- Hollis Barclay's party!!
Their lives explode in chaotic mess, flying shrapnel hitting Rex Lowe and he becomes collateral damage, thus connecting them forever.
But there's another silent, abandoned victim who becomes the central pawn in the most elaborate and bizarre revenge saga I ever did read.
The twist comes out of nowhere and smacks you in the face.
WTH just happened and Whos & Whys will leave you reeling!! “Did. Not. See. That. Coming”
Cami is strong, beaten down but rising phoenix. A brave soul indeed. Rex Lowe is a true saviour, he steps up where most would've fled.
“We. There was that we again that she wanted to cup in her palms like a treasure, afraid that it’d be taken from her if she didn’t protect it. Knowing it wouldn’t be hers for long, no matter what.”
Cyrus Sanders is ultra smart, observant, fantastic chess student which helps him strategize with calm conviction. What a delight to see him perform!!
But the accolades belong to another person hiding in plain sight. What they do to move the story forward, keeping an eye on everything, and sneaking in when wanted was simply brilliant.
Every story by Mia brings me to my knees. Her trope/genre range is vast and diverse. Uniquely penned stories with immemorable characters. I can actually recall any character of her story at any given moment of time. Such is her impact.
“5 stars for Do-Overs”

Provoking but not suspenseful
Format: Kindle
Mia Sheridans thrillers are one of my top favorites, her writing style is so raw and beautiful. I wanted to love this one as much as Bad Mother or All the Little Raindrops but it just didn't hit the same mark for me. The book starts off with a bang, but soon becomes a bit more dormant for the middle portion. I still enjoyed the book, but I think I had a preconceived notion it would be more along those lines, I felt the plot of this one wasn't as suspenseful, it was fairly straight forward which is fine just not what I expected. Or maybe I'm just desensitized from all the thrillers I read. I did love the themes of how trauma, resilience and love weave together, a chance at a do over. I also felt Seraphinas portion was a little clunky and illogical in the overall storyline. Regardless I love Mia Sheridans writing and won't stray away from her thrillers.
