Apples Should Be Red, by Penny Watson
This was a short book, but a powerful one. The hero and heroine are older, with grown children of their own. Very set in their ways, I’d say this might fall into the “enemies to lovers” category, although I don’t see a whole lot of the insult trading or passive aggression that I often see in stories with that trope. Overall, this book was very sweet, very refreshing, and the ending made me absolutely giddy.
I’ll definitely be checking for other books by Penny Watson.
