   Summary

   Roman is your average college student. Overworked and underfucked. Too little sleep and too much caffeine.

   However, she starts to find that her serious lack of sleep is leading to some crazy dreams.

   Dreams in which she's now a skeleton, with three alternates, and a buncha other skeletons that seem hell-bent on trying to get her to understand that she's not in fact in a dream after all.

   Will she ever believe them? And how much will it take her to get there?
