Fire 4 ¾ stars
Format: Kindle
Set against the backdrop of California fires, this is a story of Ali finding her forever family. Luke, Becket and Hunter own a winery that is close to the fire. Every day is a wait and see if they are going to lose their home. Ali, an aspiring artist, applied to be the nanny to Luke’s son. The attraction was obvious from the very beginning. Once Ali decided to let go, the steamy scenes were unstoppable. I like that the author showed the readers not just the relationship between her and the guys. The story also showed how the three are close to each other. It’s a good bedtime read. I received an advanced copy and voluntarily chose to review it.

Great Read
Format: Kindle
The interview was perfect and the way she ran out thinking the worst is so something I would have done. When Luke goes out to get her and asks her to stay is even better. The way Beckett acts is the complete opposite of Luke and Hunter. They all have different personalities but they each pull something different from her. They way they work as a team to save everything was just part of what shows what a future could look like for them. I would love to read more. I received a free copy of this book via Booksprout and am voluntarily leaving a review.
