I'm the Reincarnation of a Love Story

Samantha, an old soul, lost her ring while exploring a haunted house with her brother. While trying to retrieve it, a Spanish-decent lad helped her out of nowhere. The story unfolds over series of flashbacks that Samantha sees in her dreams, one of those including the lad who helped her. She then realizes as the story progresses that Arkin, the guy who's helping her all the time was in fact a ghost from her past, or probably from her previous life. She then discovered a disturbing secret in her family's history.
