Mystery by Moonlight

A mountain lake harbors a hidden past!

A charming lakeside cottage should be the perfect vacation spot for Nancy and her friends. . . until Bess becomes convinced that they're sharing the place with ghosts. Strange thumps in the attic put them all on edge except there is no attic. And worse, their neighbors, who are definitely alive, are giving them grief.

To add to the chaos, a pair of bird-watching photographers sets dangerous traps in the woods, a summer camp director chases Nancy and Ned off his property, and the assistant curator of a nearby Native American museum warns them to stay away from an ancient burial ground. Then a surprising discovery reveals a long-lost mystery and a family secret as black as night.
