The Sullivan and King families live in the same quirky little town and there's some sort of conflict between the families. Book 5 Just Say Yes in the King family is the conclusion of this world per reviewers, where all loose ends are concluded and you see everyone once more.
Thank you so much, Dandelion for completing the King family!
