The Novellas are the Best Part of This Series

 Hometown Heartbreaker by Maisey Yates 

If this is book 3.5, then why was it attached to the end of book 4? This was a novella so it was supposed to be fast paced, but this was fast paced. Casey is a drifter who ended up in Copper Ridge when her car broke down. She's living in a tent at the camp grounds and working at Ace's bar. Aiden is as straight laced as they come and they meet for the first time when he has to pull his alcoholic father out of the bar and drag him home. He leaves his father's keys with her and says he will be back for them tomorrow. She borrows the car because it'll be much faster than walking back to her tent. But, when he shows up for the car the next day, it's gone. Just as he's trying to figure out what to do she pulls in. They agree that he will meet her after work, she will follow him home in the car then he will take her back to her place. When they get to his parent's house his mom invites her in, feeds her, and offers her the use of the trailer on the property when she finds out she living in a tent. When they get to the tent it escalates. She ends up staying with him instead of in the trailer. After about a week things are going well until his dad's truck gets repossessed and they get into a screaming match about the farm. She tells him she loves him and he doesn't say it back and basically tells her she doesn't know what love is. She leaves. He is miserable. He goes to the bar, apologies, and asks her to stay. He stops taking care of his parents and they sell the farm. He gets a rental and goes to work for the Garrett's. Fast forward 2 years later, they are still together. He bought some land so they can build their dream home and the book ends with him proposing.  Insta-love isn't high on my favorite tropes, but I don't hate it either. It works for a novella.
