Phantom Heart by Kelly Creagh

Seventeen-year-old Stephanie Armand doesn’t believe in ghosts or spirits. Despite her six-year-old sister, Charlie, insisting a masked figure is hiding in her closet, and the rumors at school, Stephanie isn’t convinced her father’s latest renovation project–a crumbling Victorian mansion–houses the soul of a monster.

So when the very charming (and paranormal obsessed) Lucas Cheney takes an interest in both Stephanie and her notorious home, the supernatural and romantic activity escalates to an all-time high. And that doesn’t even take into account the dashing, British-accented eighteen-year-old boy, Erik, who’s taken up residence in Stephanie’s nightly dreams. A boy who may have something to do with the man in the mask, and the strange occurrences taking place at Moldavia.
