Dog Person by Camille Pagan

Miguel is the owner of Lakeside Books, which sits in a tourist town on Lake Michigan. He hasn't been the same since his wife Amelia (a romance author) died more than a year ago. In fact, the bookstore is now in danger of closing after bestselling author Jonathan Middleton-Biggs didn't show up for an author event Lakeside was hosting. Miguel decides to try and find Jonathan so they can do a makeup event, but instead he meets Jonathan's sister Fiona and niece, who coincidentally is named Amelia Mae. Told through the eyes of Miguel's and Amelia's dog, Harold, Dog Person is a story of love, loss, and second chances.
