The Prince Has No Pants

All life on Earth has been stolen away by The System.
It was transported to another world at the behest of a distant galactic empire that lives in terror of humanity’s potential.
Ben – just a normal, if not slightly above average guy –  had been about to go on the first real vacation of his adult life. But plans changed. Now, he must contend with danger and mystery in a world full of monsters, magic, and treasure. Armed with nothing but his wits and a special item given to him by The System, he embarks on a damn good adventure.
