M-Series Super Fire Spark Plugs
HKS M-Series spark plugs are high performance Iridium plugs designed to provide improved ignition performance, durability and anti-carbon build-up.
- 0.6mm Iridium Alloy Center Electrode
- Outer Electrode with Platinum Chip
- Short Type Outer Electrode (Anti-Vibration)
- Thermal Edge
- Spark Support Gap
M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.
The Iridium alloy is used because of its durability and reliability. On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity. With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration. The Iridium plugs are available for multiple applications and offered in "colder" heat ranges of 7 and up and specifically for rotary, heat ranges of 9 and up are offered.

Loved this book so much
Format: Kindle
First, it’s a cute story with a great themes of: younger older woman, daughter‘s friend, disgruntled with family. I have to admit every time the main character was talking to her father I was so incredibly annoyed. It brought up all the conversations I’ve ever had with misogynist in my life. Definitely well written.
On happier notes; the love story, the meddling neighbor/landlord, cute child, and kittens! Really, what story isn’t made better by kittens?
Seriously this is an exceptionally well written story with fantastic characters, plot lines, and a great ending.

A Thoughtful and Compelling Romance with Depth and Maturity
Format: Kindle
Miranda MacLeod and TB Markinson deliver a compelling and emotionally charged romance in The Anatomy of Forever, a novel that successfully balances personal transformation, ethical dilemmas, and the weight of professional responsibility.
Dr. Rowan Colchester, newly embracing her true self after a difficult divorce, is not prepared for the whirlwind that follows a passionate encounter with a younger woman. When fate reunites her with Dr. Simone Doucette, an idealistic doctor seeking solace in a Cape Cod ER, their undeniable connection becomes fraught with complications. The revelation of their unexpected personal link adds a layer of tension that challenges not only their burgeoning relationship but also their careers and reputations. As the stakes rise, Rowan and Simone must navigate professional ethics, small-town scrutiny, and their own vulnerabilities to fight for a second chance at love.
While the “sleeping with your daughter’s best friend” trope initially presents a hurdle, the novel compensates with a well-developed plot that offers depth beyond the romance. MacLeod and Markinson craft a narrative rich with stakes that extend beyond the personal, grounding the story in a high-stakes professional and community-driven context. The characters are well-drawn and compelling, both Rowan and Simone stand out as confident, determined, and capable women who refuse to be defined by societal expectations or past mistakes. Even secondary characters, such as Erica, evolve in ways that add nuance to the story.
A refreshing aspect of The Anatomy of Forever is its portrayal of strong, independent women who communicate effectively and fight for what they want. Rather than relying on contrived misunderstandings or overplayed angst, the novel explores mature relationship dynamics, making the romance feel authentic and rewarding.
Overall, this is a well-executed sapphic romance that offers substance, well-rounded characters, and a satisfying blend of personal and professional stakes. MacLeod and Markinson have crafted a narrative that is engaging, thought-provoking, and ultimately, deeply satisfying.

Lives up to all the hype
Format: Kindle
Stars: 5 Stars
Format: Audiobook
Narrator: Lori Prince
Series: Stand Alone
Steam Level: Steamy
I read this for the 2026 A to Z Book Challenge for A.
This was the first book I added to the A to Z Challenge because I was so excited to read it and it absolutely lived up to all the hype.
Quick Thoughts:
- There is something about the “we had a one night stand but didn’t know we both have the same person who is important to us in our personal lives” set up that I just have so much fun reading
- The trauma that Simone went through as a kid then again as an adult was absolutely heartbreaking
- Two things I really liked about this book is that it didn’t end when they got together and that the Big Third Act Drama wasn’t about them being together
- This is exactly how cats get adopted
- No third act break up!
- I hope Lance ends up in prison
- The character growth almost everyone in the book goes through in this was wonderful to watch
- I had the biggest grin with this ending. It was sweet and adorable and perfect and just made me so happy
- It is ALWAYS a joy to listen to Lori Prince. She did a fantastic job, as usual, and I sincerely hope to listen to a thousand more books of hers
Overall I loved this book. T.B. Markinson and
Miranda MacLeod, by themselves, are an auto buy but when they write together I actively stalk their new releases to preorder it the second I can. I can honestly recommend any book of theirs without having read it.

A Story Of A Two Conflicted Powerhouse Woman!
Format: Kindle
The writing dynamic duo has once again brought us a story so big in chemistry and family. Two very different woman meet in a bar and decide to have a night they will remember. Although there is intense chemistry, one is leaving for another country and the other is replacing her ex in his powerful position. Two years later, these two woman meet again but it is where they both work and one is best friends with the others step daughter and the other is the boss. A web neither wants to cross but the hearts have other ideas. The supporting cast to these two women are just as good as the lead. But each time they get closer to a maybe, something comes between them which brings more problems. A well worth read. It has laughs, tears and family drama. Another great score for the writing duo.

The dynamic duo has done it again!
Format: Kindle
I think TB & Miranda are my favorite writing duo. I love all their books whether written independently or collaboratively. Although this is an age-gap story of two doctors, Rowan and Simone, it's a mature telling of two very independent yet professional women with a lot at stake in their careers, as well as their personal lives.
In addition to the MCs, the secondary characters added extremely juicy conflict and delightful humor and levity. I especially loved Marigold and her free spirited young daughter Poppy.
I wasn't sure how the ethical dilemmas would be solved, but these fabulous authors wrote a very thought-provoking and satisfying ending. Well done, you two! I wholeheartedly recommend!!!
