After suffering a personal tragedy Abby Sullivan buys a huge old seaside mansion she has never even seen, packs up her life in San Francisco, and moves to Holiday Bay Maine, where she is adopted, quite against her will, by a huge Maine Coon Cat named Rufus, a drifter with her own tragic past named Georgia, and a giant dog with an inferiority complex named Ramos. What Abby thought she needed was alone time to heal. What she ended up with was, an inn she never knew she wanted, a cat she couldn't seem to convince to leave, and a new family she'd never be able to live without.

In book 20 in the series, It's Halloween in Holiday Bay and the whole town has pitched in to ensure that the Harvest Festival is the best one ever. As they do every year, Abby, Georgia, and Jeremy have planned several Halloween themed events for the Inn, which will take place alongside the events hosted by other merchants in town. Things are right on track and expectations are high until the body of a close friend and coworker is found tucked in amongst the vines in the pumpkin patch.
