Planners are great for to-do lists, keeping track of appointments and . . . scheduling a murder.

When Thea Olson returned to her hometown of Why, North Dakota, for the Fourth of July, the last thing she expected was to add "investigate a murder" to her to-do list. But when her cousin is falsely accused of killing her business partner, Thea is drawn into solving the case. In between hunting down clues and interviewing suspects, Thea learns more than she wanted to know about creative planning, stickers, washi tape, and glitter pens.

Can Thea clear her cousin's name or will she become the murderer's next victim?
