A new age time travel fiction.  Christine is given the chance to change the past due to a freak encounter with her younger self through a Facebook fluke.  She warns herself about a future tragedy involving Christine's children. She gives herself a head start on treating her rheumatoid arthritis. She even mentions some football stats.  But how does Christine really know if the encounter is real? And if it is? Could she really change anything? If so, at what cost? "The movie Frequency meets the movie The Lake House meets the digital age."
