This book was a disappointment. I love fantasy, Sci Fi and the reviews for this led me to reading it. The plot had too many coincidences for me. Mom, altho insane just keeps turning up at the right time to aid in the cause. The mutated younger sister is supposed to be some sort of cannibal but is able to resist the urge around her family. Call me picky but I had a hard time getting into the picture here.
