Christopher Columbus Saves the World

When a group of too-smart-for-their-own-good graduate students enlist a 20s high school drop out named Christopher Columbus to be a test subject in a series of top-secret, cutting-edge physics experiments, Chris jumps at the chance to explore the boundaries of time and space. But Chris soon finds out that the fabric between worlds is more fragile than he ever expected, and any simple mistake could leave his very existence - along with everyone he knows - hanging in the balance.
