Penny's reluctant stay at the Black Butterfly is interrupted by two ghosts (one friendly, one not), and a potential first love in this spooky-sweet story set on the mysterious coast of Maine.

Sixteen-year-old Penny is furious that she has to spend Christmas break alone at the Black Butterfly, an old inn at the coldest, bleakest edge of America--an island off the coast of Maine. This trip is the brainchild of Penny's flaky, ghost-hunting mother, who leaves Penny at the Black Butterfly so she can hunt ghosts across the country in Idaho. Penny does not believe in ghosts until, that is, she discovers two very real apparitions living in the Black Butterfly--ghosts only she can see. Her abilities become even more complicated when she meets George, the handsome son of the inn's owner. Although Penny wants to remain aloof, she finds herself drawn to George, maybe even falling for him. Unfortunately, with her mother's history of ghost-hunting at the inn, Penny knows she can't tell a soul about what she's seeing and experiencing, or that one of the ghosts wants her dead. Left with no one to confide in, Penny must figure out who to trust and how to survive her time at the inn ... before it's too late.
