Mystery in the Keweenaw Peninsula

You met Jane Bowman in D.J. Martin's first book 'Mystery in the Porkies'.
In this sequel the young history teacher and amateur archeologist has not just accepted her intuitive skills,
but she has sought out the advice of a family friend and learned more about her inherited gift.

When she decides to volunteer for a huge archeology dig in and around the ghost towns of Michigan's upper
peninsula her intuitive talents unfold. She joins a hundred other young archeology volunteers on an adventure
that will truly test her skills. But archeology isn't the only thing going on in the copper country ghost town she's
been assigned to.
Learning who she can trust becomes paramount as a determined Indian ghost tries to tell her an old secret.
She's intrigued, but she also knows that she can't go on this journey alone!
The question! Who can she trust?
