Series information from Goodreads.

"Seventeen-year-old Stephanie Armand doesn't believe in ghosts or spirits. Despite her six-year-old sister 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, Moldavia, the supernatural and romantic activity escalates to an all-time high. But then there's Erik-- the dashing British boy, seemingly from another era, 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"--,Provided by publisher.
