It's the 4th of July in the Wisconsin Northwoods, and no one is more excited than Emmy Cooper. She's happy to be back in her hometown, settling once again into small-town living and helping her family run Cooper's Cove, their lake cottage resort. Emmy and her teen crush, police officer Dean Erickson, are enjoying getting reacquainted, while she and bestie Whitney are closer than ever.

Lake Covington and its quaint namesake town are bustling with visitors celebrating during the annual three-day Independence Day Freedom Fest. Everything is Yankee Doodle Dandy until a local man with a reputation for trouble starts fireworks of his own. And the explosions just keep on coming when Emmy stumbles over a dead body at the celebrations!

The dead man is Jordan James, and as Emmy soon finds out, there are no shortage of people who might want him dead. From a jealous jerk to a conniving cousin and even a former friend from his past, suspects are more plentiful than ants at a July picnic! Despite promises to stay out of the investigation, Emmy finds herself smack in the middle of it. Can she and Whitney figure out the truth and find liberty and justice for all?
