When Arnie refuses surgery for his bum knee, Laurel takes the family on a relaxing trip to the beautiful sunset coast on Lake Michigan to recuperate. Accompanying them are Arnie's sixteen-year-old son, Sawyer, and things are made even better when their close friends Claire and Charles join them for a visit. The area is known for sand dunes, white beaches, and swimming. An odd manifestation of bioluminescence-floating lights on the lake-creates an eerie prediction of things to come. One that Sawyer jokingly points out because anytime his parents and their friends get together, disaster strikes. But this time it's Sawyer's girlfriend who proves to be the catalyst for trouble when she takes a job at Dune House as a live-in scribe for Maeve, a dying author who sees the ghosts of dead children. When Felicity mysteriously disappears, and then others follow, it's apparent that Sawyer's prediction has come true: trouble has come to Lake Michigan. Following forensic botany clues, Arnie and the remaining group desperately search for the others and walk right into danger. Will Arnie find everyone in time? What mysteries does the Dune House hold? Find this out and more in , Deb Davies's latest Coast-to-Coast Michigan Mystery.
