A mystery and a healing journey for 3 people
Format: Kindle
⭐⭐⭐⭐ 🌶️🌶️🌶️ Touch her and 💀 🍑🍆🍑 MFM/Why choose 🤓Military MMCs 🥺Damaged hero 🤯BIG mystery to solve 🐶Lovable fur bestie 😈Forced proximity My Thoughts 💭 I definitely feel the book is contemporary but there are some dark sides to it just because of their past and what they went through within the military as far as the guys. I can say that I do love how Aiden and Miles are such good friends and how they stuck together and have helped each other. Aiden is very goofy and free willing but has a lot of guilt and almost in a way self-conscious. As were Miles gives off a dark and broody daddy vibe and Aspen ends up being the one to just unravel him. I do love Aspen work and how she overcomes what she's been through and how she sees her growth and her self-worth and decides to put herself first. This is a very much meat cute moment just because of the way they meet but then you have the backstory of like Miles and all of that... I feel that the underlying plot of the mystery aspect really keeps you entangled into everyone else as of the side characters so I'm excited to see more of the series. Spice is that a three just because I feel like there was so much more to their relationships and their interactions that the spice wasn't the forefront of it which was good because they needed to grow all three together and you need to see how they interacted separately and there was a lot of trauma healing in this book so it's understandable why the spice isn't the forefront. I would say that if you're looking for something that is going to be sweet but yet pull at your heartstrings this will be the book.

I'm hoping some things will be wrapped up in book 2 but with the epilogue for this book being a year later I'm currently just confused. Otherwise a very good read.

Love, Love, Loved!!
Format: Kindle
This book was a wild and fun ride. It has suspense, it has found family and most importantly it had so much true love and friendship. I fell in love with Miles and Aiden instantly. The love and affection between these two friends was so profound and deep you just instantly wanted them to find their HEA. I absolutely loved how they supported one another through all their hurt and trauma. They have this unbreakable bond that is truthful and real. It’s simply beautiful how they hold up one another no matter what. When they meet Aspen not only does she fit into the town so perfectly, but she is able to appreciate each man for who they are instantly. She’s a great FMC in that she’s so kind, genuine and willing to trust again even when she’s been hurt by people in her past. This book had a journey filled with so much love and healing that my heart cried several times. Each character was able to not only break through walls, but help one another grow into better versions of themselves. The love that flourishes when all three come together was electric and passionate. The spice was steamy and the romance was swoon worthy. The mystery throughout the book is one that isn’t completely solved in this story so I’m looking forward to the next book in the series and of course seeing more of Miles, Aiden and Aspen. 5 stars!

Miles, Aiden, and Aspen
Format: Kindle
Man this was a great start to a series. The author got you hooked one the book from chapter one. We are still don't have all the answers but they will come in due time. I absolutely enjoyed this story. Miles seriously has my heart. He was just such a lovable guy. He served his country and was injured doing his job. He carries around a lot of trauma and emotional damage from that time. His childhood best friend Aiden feels guilt over what happened to Miles. He blames himself even though it was not his fault. Due to his trauma they form an unlikely pairing. They need each other and to share the person they are with due to Miles's trauma. They met Aspen and form and instant connection. Little does Aspen know that she has helped Miles during some of the worst of his times with her beautiful pictures. She is running away from a relationship and a job that literally used her and tossed her away. She forms an instant connection to both guys and Miles's dog Jubie. She teaches them both to not only forgive their past but also love themselves more. She is everything they need in their life. Mean while there is a killer/stalker running around causing havoc. Will we find out who the bad guy is? I guess we will have to keep reading the series to find out. I really enjoyed this book and I think the author did a great job keeping your interest. I cannot wait to see what else she has instore. She had great world building and character development.

Rediscovering herself and finding the unexpected
Format: Kindle
First we have Aspen a young woman who lost herself to her ex and what he wanted. She ran to Alaska to re-find her love of photography and the outdoors. While she did find this she also found a broody and overprotective former Navy Seal who still had a lot of healing to do, his super sweet over thinking best friend and their lovable doggo. I absolutely love the different plot lines going on in this story. It leaves mystery and a sense of foreboding around every turn. Of course this doesn't answer all the question we have for Anchor Bay because this is only book one but I absolutely love the community they have. Aspen has an immediate connection with the two friends. She has an easy and open demeanor that puts even the broody guy at ease enough to engage. Aspen is sweet, open, and genuinely cares about the people and animals she comes in contact with. I can't wait to see what is next in Anchor Bay.
