Her Favorite Therapist: A Psychological Thriller

Mia Thorton #5

by Magdalin Laine

Marriage was never easy for the DeLuca’s, but after the last murder, Mia is ready to quit.
Fuck the contract, fuck appearances, and fuck her husband.
She has nothing left to lose.
But Kit won’t let go. And all the trouble only lands her in the cruelest punishment of couples therapy.
Dr. Mackay comes highly recommended. Esteemed, unshakable, and bound by ethics. He’s determined to stay neutral as he guides them towards healing. And most importantly, he’s no stranger to the unspoken family business.
But with a patient like Mia, hellbent on self-sabotage and destructive patterns, conventional tactics won’t cut it. If he wants to reach her, he’ll have to bend the rules and try an unorthodox type of treatment.
Will his unusual methods break through to her?
Will he be able to salvage the broken person she’s become?
Or is he going to fall victim like everyone else in her game of love?

⭐⭐⭐⭐⭐ Five-Star Review

Her Favorite Therapist: A Psychological Thriller by Magdalin Laine is dark, provocative, and psychologically unhinged in the most delicious way. This book messed with my head and I loved every second of it.

From the opening pages, you’re dropped into a marriage already cracked beyond repair, drenched in secrets, violence, and emotional decay. Mia DeLuca is not a “likable” FMC and that’s exactly what makes her fascinating. She’s sharp-edged, self-destructive, and brutally honest about her desire to burn everything down. Her voice bleeds rage, pain, and control, and you can’t look away.

Enter Dr. Mackay calm, composed, and supposedly bound by ethics. The therapy sessions are where this story truly shines. The power dynamics, the manipulation, the blurred lines between healing and obsession… it’s a slow psychological unraveling that feels intimate, tense, and deeply uncomfortable (in the best thriller way). Every interaction crackles with danger, and you’re constantly questioning motives, reliability, and who actually holds the power.

What impressed me most was how the book refuses to play it safe. This isn’t a clean psychological thriller it’s messy, morally gray, and emotionally invasive. The “unorthodox treatment” isn’t just a plot device; it’s a descent. And watching whether Mia is being saved, studied, or consumed kept me hooked until the very last page.

If you love dark psychological thrillers, morally questionable characters, taboo tension, and stories that crawl under your skin and stay there, Her Favorite Therapist is a must-read. Disturbing, addictive, and impossible to forget. 🖤🔥

Mia and Kit are going to couples’ therapy. They are having issues with their marriage. Dr. Greer Mackay is the therapist.

I enjoyed Mia. She doesn’t have a filter. This book is really about her. Her husband and the therapist are secondary to her. She seems to be able to draw men in and drive them insane. No one is safe not even Dr. Mackay.

This was a crazy book in a good way. The story draws you in as Mia has issues. It is fast paced and we learn about her past. There is lots of spicy action. Apparently this is the latest book in the series featuring Mia so I might just put the previous books on my TBR list.

I received a free copy of this book via Booksprout and am voluntarily leaving a review.

Different is how I would describe this book about a marriage on the rocks and the impact therapy in the right or wrong hands can have.
Will conventional ambivalence serve the psychotherapist, or must he employ extreme tactics to impact his patient? Moreover, is this a case of the tail wagging the dog? What came to mind more than ever for me was the saying that those who go into mental health do so because they themselves are in need of mental health help. 4 stars

I wrote this book so I'm going to throw five stars at it, haha. But in all honesty, I'm really excited as I go through the last edits and revisions before bringing this book to the world and letting y'all read it. I had a lot of fun with it, the plot is unhinged, over the top, the steamy scenes are intense, the moments are drawn out, and the characters get exactly what they ask for and then regret it.

All these books are trauma porn, but this one is peak.

This book made me feel literally everything that was said to happen to the FMC which in this situation was not really good. This book had such a huge plot twist that I literally had to put my kindle down and breathe and think about it because.. what??
This book is really good for absolutely everyone who has ever gone to a therapist of had ever felt struggles in a relationship.
Really really amazing book
