Nine Feet Under: Book Three in the Caching Out Series

Margarita and Bindi have big plans for the Fourth of July, involving borrowed bicycles, a geocaching power trail, live podcasts, and plenty of fun. But their day quickly goes awry when they stumble upon what looks like a murder in progress.

Strange rivalries and secret alliances test Margarita's puzzle-solving skills, and Bindi suffers a rather painful setback when she comes face to face with someone she never thought she'd see again.

The overly stoic sheriff can't be in two places at once, so the girls need to figure out whodunit and rescue the next potential victim before the explosive finale.
