Everyone could see it coming. But one man could do something about it. Oh, he couldn't avert the nuclear holocaust, but a scientist in Austria, ruthlessly using billions of research dollars for his own purposes, set himself up and out: he created a time machine, and filled a warehouse with low-tech survival gear. Too bad he didn't get to use it himself. Instead, a team of American grad students, led by their professor, is sent back to the late Roman Empire. Even though they are experts in this time and place, they are about to realize that books and actual experience are very different things.

A portal opened, and Perry's curiosity got the better of him. Once. Twice. Three times did Perry step through a portal, each to a new and strange world. He stepped through into a world of advanced technology, power armor and micro reactors.

One week. If you survive, you choose a Cosmic Power ... If you survive. Jace isn’t one to give up. Not when his sister dies. Not when he loses his legs. And definitely not when The Cosmic System takes over Earth.

Clio isn't a thief. She isn't a spy, a soldier, or a diplomat. Aside from her rare ability to mimic spells, her only notable talent is gardening.

Their stronghold is located deep in the Underworld, which is exactly the sort of place an Overworld nymph like her should never go. Getting in won't be that hard. Getting out alive is the impossible part.

Have you ever come across those stories with heroes who knew just how to get things done? The ones who were masters in five different martial arts, and knew ten ways to skin a bear after killing it with their bare hands? Yeah, that wasn’t me. Hell, I had trouble asking a girl out on a date. But someone in clerical must have made an error. Because I got ripped from an airplane on my way home after my last day in the Coast Guard. I mean, come on, I wasn’t even in one of the hardcore branches of the military or anything!
