Book excerpt: Minnie and Ben are back for more murder and mayhem! Minnie Crockwell, recreational vehicle enthusiast and traveler, and her ghost companion, Ben, are heading to Devils Tower. The massive monolith dominating the Wyoming landscape is the stuff of legends...and mysteries. One such mystery finds Minnie and Ben before than they find him. A little green man/alien leads them on a merry chase to solve the Trouble at Devils Tower. Each story in the series can stand alone, but to avoid extensive repetition of the backstory, the books would be best read in order.
