Finding Hope Trilogy

What if the life you've known is not the life you've lived? What if the reality you see everyday is not your real life? What if the strange dreams you've been having tell the real story of your life? Cassy and Cindy Wilmark know nothing but their poverty-stricken life, but when an army arrives at their door and Cassy is suddenly plagued with memories of a past life she doesn't recognize, their worlds are turned upside down. Can these two sisters separate reality from fantasy, or is the fantasy their reality?
