President John F. Kennedy's counterpart from an alternate reality visits Earth, his stated mission: to observe our timeline, including the assassination of our president. But then his own dark fate is revealed, and he goes on the run. Soon Kennedy finds himself in a battle to save both his universe and ours from marauders who would do anything to destroy us. To stop them, he must trust a mysterious faction from yet another reality, the Martians. This work of alternative history/speculative fiction creates a subgenre aimed at those who relish far-out concepts containing a strain of plausibility. Here's a universe and an Earth that match scientific theory and offer unique ideas within the realm of the perhaps might-be.
