The mirrored image is, at best, two dimensional - it certainly is not three dimensional or multi-dimensioned. As a result we see only the exterior of the image being reflected and that eliminates the possibility of any interior vision and insight. At Mirror Falls and in the Ranges where the women hiked we see mirror images or face-front images of the environment and the women themselves, but we cannot look into their minds, experience their deeper thoughts about their siblings or children, and this contributes to the building mystery. Much description is provided for surface images of each - thus we see the twins do not look alike, the children of Alice and Lauren are clearly depicted - one very pretty and the other the mirror opposite - yet we cannot see inside them - what has contributed to or caused their personal
traumas. Even their mothers do not appear to have that insight. Erin Falk, however, the author's main and continuing character, is struggling with looking within - and Carmen serves as his mirror - more successfully enabling him to begin to see his real self and situation and confront it by book end.
