A murder. A secret. A promise.
Gretchen Lauterbach's grandmother asks her to fulfill a strange request that involves her older sister Rachel, who's been exiled from the family for the past five years as well as giving her a map. In this case, instead of an X marking the spot of buried treasure, Gretchen finds buried secrets. Until now Gretchen hasn't been able to get herself emotionally ready to read her sister's letter. When she does, she gets the shock of her life.
On a path that only seems to get stranger by the minute, she finds herself reuniting with family she never realized she had. She also discovers a lover's remains have been hidden in the black hills of France's Morvan forest. In order to right an old wrong--and save her own life--Gretchen must distinguish ally from foe, truth from lie. Nothing is as it seems beneath the Morvan moon.
