'An Impossible Truth' is the first book of a pentalogy and tells the story of twenty-six-year-old Sophia McAllister who finds out her dreams are not just dreams: she travels to a realm, much like her own, except she's sixteen and back in high school. But her travels come with a heavy price; her own sanity is on the line when she starts to question whether or not the life she's led so far is in fact... real.
