She had arranged to meet her husband in Northern Ireland for a second honeymoon, but when Charleigh arrives at the remote castle, she receives a message that he won't be coming—and that he's leaving her for another woman. Stranded for the weekend by a snow storm that has blocked all access to the castle, she finds herself three thousand miles from home in a country she knows nothing about.

She is soon joined by Sean Bracken, the great-grandson of Laird Bracken, the original owner of the castle, and she finds herself falling quickly and madly in love with him. There's just one problem: he's dead.

As the castle begins to come alive with secrets from centuries past, she finds herself trapped between parallel worlds. Caught up in a mass haunting, she can no longer recognize the line between the living and the dead. Now she's discovering that her appearance there wasn't by accident—and is more earth-shattering than she ever suspected.
