It takes a community
Format: Kindle
A beautiful depiction of Celeste and Natalie’s journey to discovering their true purpose. Natalie began as a thorn in Celeste’s side and ended up being her true soul mate. I loved Celeste’s family tradition of feeding those less fortunate. One recipient’s, Sean, life was transformed into a productive and joyful one. It was beautiful. You could see Celeste’s heart, even though she tried to keep it secluded behind walls. Natalie brought the joy of the holiday spirit to Celeste and once she acquiesced to supporting Natalie’s vision, it was transformative in the entire community. A very good, sweet read. I unequivocally, heartily, and enthusiastically recommend this and any other works by TB Markinson and Miranda MacLeod. I own most of them and have never been disappointed. Thank you Peace

𝙼𝚢 𝚃𝚑𝚘𝚞𝚐𝚑𝚝𝚜:
I am totally obsessed with 𝙉𝙞𝙣𝙚 𝙈𝙤𝙣𝙩𝙝 𝘾𝙤𝙣𝙩𝙧𝙖𝙘𝙩 by Amy Daws! This book is everything I never knew I needed in a romance—heartwarming, steamy, and full of emotional depth. Trista and Wyatt's story is a thrilling rollercoaster adventure. When they enter into a surrogacy agreement, they are both focused on their own goals. However, they soon realize their connection is undeniable, and what begins as a business arrangement quickly evolves into something much deeper.
I loved watching them navigate their complex emotions. Wyatt's tough exterior hides a vulnerable side, while Trista's humor and passion are the perfect counterbalance. The banter between these two characters is fantastic, and the slow-burn tension is just perfect. Amy Daws skillfully balances humor with emotional, heartfelt moments, making this story a joy to read. The family dynamics, especially in Wyatt's Family, added much richness to the narrative. I found myself smiling through many parts of it. It's touching, funny, and just the right amount of steamy. If you enjoy a small-town romance filled with spice and a lot of heart, you absolutely need to read this book!
🎧️Teddy Hamilton and Erin Mallon did a fabulous job bringing Wyatt and Trista's story to life. If you enjoy audiobooks, this was a delightful listen.

“How am I supposed to remain the mysterious, grumpy brother if word gets out I’m a softy?”
Format: Kindle
4 - ⭐⭐⭐⭐
“How am I supposed to remain the mysterious, grumpy brother if word gets out I’m a softy?”
Nine Month Contract is the first instalment in the contemporary romance series, Mountain Men Matchmaker. Each novel in the series is an interconnected standalone that follows a group of brothers. Written in multi first person POV, the story primarily follows Trista and Wyatt as they enter an surrogacy agreement that draws them together in ways they did not imagine.
Trista has a dream to open her own animal shelter but money is tight. Through her investigation she is tempted by the idea of surrogacy but no surrogacy agency will accept her because of her plus size figure and her lack of pregnancy experience. Add in her apartment tenancy becoming precarious and she needs a miracle...enter Wyatt and his tenacious niece.
Wyatt has decided he wants a family and while finding a significant other may not be in the cards, a child is something he can achieve...except finding the right match has proven to be challenging, too. When his niece comes across Trista it sounds like a match made in heaven - she saves him thousands on a surrogacy agency and, in turn, he offers her room and board during her pregnancy (on top of the surrogacy fee). Except what happens when the more time they spend together the more time they begin to wonder...could there be something more if they gave it a chance?
This book was enjoyable with a surprisingly deep conversation on self worth and independence!
Trista is a very strong and independent woman as a result of her life. I felt for her because she always questions the support she is offered as if she can't trust it. She wants what Wyatt is offering but she tends to lash out in fear it will be taken once she feels comfortable. Her passion for animals really shows her empathy and care. I did want to shake her a few times but she had a lot of baggage to work through.
Wyatt wants to be a dad so badly. He has been burned in the past and it definitely haunts him. He isn't extroverted so when he makes a true connection it matters. He can be possessive and blunt but there's an underlying element to him that desire to support the people he loves. I adored the way he worked around Trista's need for independence while still providing help. His relationship with his niece is also cute.
“If we do this…you need to know that means I will own your body. Every particle on your skin will be mine for the taking. Do you understand?”
In terms of spice, I would place this at 3.5 spicy peppers out of 5 spicy peppers. There are about 6 spicy scenes across this book. The initial spice scene (25%) is self pleasure as the characters complete each part of the surrogacy but next spice isn't until the 57% mark and then we get quite a bit of spice onwards. Our main characters have excellent chemistry and can't keep their hands off each other once they start. It is explicit and detailed and they like to have fun in riskier locations. The spice was also varied to keep things interesting. Wyatt is very possessive during spice and it made for some very HAWT moments. I had fun with it!
The story itself is fairly character driven. I felt the pace felt pretty even and we really go to explore Wyatt and Trista's relationship here. I liked the connection to family at the core of the novel and the addition of rescue animals to add levity - these animals were so cute and I loved how they melted out characters. This book deals with some more serious topics around Trista's insecurities and I felt they were approached well - she often lashes out over these and Wyatt struggles with this. I felt the whole thing around Trista's friend built up to nowhere but I was more focused on the pregnancy journey here. There are some traditional elements to the romance but I like to take comfort in this. The ending is really sweet and it hits the perfect spot of not too long and not too short.
Overall, this was a fun read that kept me engaged. Nine Month Contract is perfect for contemporary romance readers who like a bit of a kick to their romance with a powerful family bond, so much banter, and adorable rescue pets to ease the journey.

Surprisingly good pregnancy story with amazing narration
Format: Kindle
This book was cute, funny, and unexpectedly heartfelt. Pregnancy plots aren’t usually my go-to, but this one felt fresh and fun, with a unique take that totally worked for me. The story leaned fully into the romcom vibes while still delivering a surprising amount of emotional depth.
I absolutely loved the cast—both human and animal. Every character felt charming and well-rounded, and the family dynamics, especially between the brothers, were a standout. Their relationships added so much heart and humor, and I’m already excited to read their stories next.
The audiobook deserves a special shoutout —the narrators were fantastic and brought the humor, emotion, and banter to life perfectly. Overall, this was a cozy, feel-good romcom that made me laugh, swoon, and smile way more than I expected.

Eh
Format: Paperback
I came for the baby contract, stayed for the banter, and left with mixed feelings.
Okay, listen. I wanted to love this book. It had all the ingredients for a delicious, spicy small-town romcom:
✔️ A broody, bearded mountain man who wants a baby but not a relationship (sir, okay...)
✔️ A scrappy, sunshine-y heroine with big dreams and zero time for BS
✔️ Forced proximity, a fake-ish relationship, and... a literal baby contract? SIGN ME UP.
BUT.
While this had moments, the overall execution didn’t quite deliver that knockout punch for me. It was cute, it was quirky, it had potential—but it also felt a little surface-level when I wanted more emotional depth.
🪵 Wyatt is peak grump. Like, grump of the year award. He’s emotionally walled-off and makes a very logical, slightly cold decision to have a baby with no strings attached.
🐾 Trista is feisty, fun, and came to this mountain town to start an animal rescue—but ends up signing up to carry Wyatt’s baby instead. Girl, blink twice if you need help.
Their chemistry? It was there, but it felt more tepid tea than slow-burn wildfire. Some of the banter made me smile, but a few moments dipped into cheesy instead of charming. I wanted more genuine connection before we jumped into big emotional decisions.
Quote that kinda sums it up:
“I don’t want forever. I just want a baby.”
Trista: blinks in rom-com disbelief
Also, Wyatt's whole “no love, just baby” rule was giving ✨robot with a sperm bank✨ vibes for too long. I wanted him to soften sooner so I could fall for him the way I know I was supposed to.
That said, it’s a fun, quick read with some sweet moments and the promise of more drama in future books. If you’re looking for a quirky romcom with a non-traditional setup and can roll with a little emotional whiplash, you’ll still have a good time.
