The Stone of Tantalus is a mind-bending journey through both time and alternate realities, and explores the nature of who we are and how we get there. Jason Callahan wants to go home, and he would if he knew where it was. For years his world has changed around him again and again without warning, leaving him with new jobs, new friends, and new enemies. One of a few travelers, Jason slips between the many universes that make up his life, moving sideways from one reality to another; he just can't control it. Worse, another traveler is is stalking him, and Jason's only assets are his wits, an uncle the family thinks is crazy, and a cryptic alternate version of himself. While many might lose their grip on reality, and others would simply give up, Jason hopes the next jump will take him home to the life and love he left behind. When the universe calls, however, sometimes you just have to make a stand.
