Famed Alaskan "musher" Jessie Arnold thinks she's finally put her dark past behind her. But the excavations on her new cabin unearth a decades-old skeleton entombed in a crumbling basement wall -- along with a butterfly pendant necklace worn by the alleged victim of a brutal serial slayer who preyed on area women twenty years earlier. Pulled once more into a murder investigation against her will, Jessie fears a grim, half-forgotten nightmare has been reborn. For, in this stark and lonely place, in the first days of the all-too-brief Alaskan summer, another woman has disappeared without a trace. The signs suggest the unthinkable: an insatiable human monster has returned. And the clues she's uncovering hint that Jessie Arnold may well be his next victim.
