Suddenly Moxie is involved in Boston's biggest unsolved mystery: The Isabella Stewart Gardner Museum art heist. Moxie has two weeks to find the art, otherwise she and the people she loves will be in big-time danger. Her tools? Her best friend, Ollie, a geocaching addict who loves to find stuff; her Alzheimer's suffering grandfather, Grumps, who knows lots more than he lets on; and a geometry proof that she sets up to sort out the clues. It's a race against the clock through downtown Boston as Moxie and Ollie break every rule she's ever lived by to find the art and save her family.
