33 Frivolous Pricks : (of time)

Danger was not on the agenda as eight time-travelers leave 2025 for a brief excursion into the past. But one of them commits a big no-no that tears a hole in the dimensions of time and space.

They come face-to-face with some of the goriest disasters and most odious crimes of the twentieth century, and the longer they stay trapped in the past the deadlier the pricks become.
