After finding a mysterious old scientific text in her College’s library, young Danni Spivey is pulled headfirst into what at first seems to be a long forgotten experiment aimed at intra-dimensional travel.

In their place are identical facsimiles, some of which are benign, while some seem to mean her harm. Danni wrestles with the idea that she might actually be losing her grip on reality. Perhaps the only thing changing in her world, is her perception of it.
