Alien twin scientists follow one another to earth from their research facility located in the ridge between dimensions in their Zodd class Ridgerunners. Alina Galina, the female twin, has stolen her brother's Quantum Temporal Singularity to prevent it from being launched against their home world's dying star. Maston Galina intends to take back his QTS and complete his self-appointed mission. Being telepathic makes finding one another easy; but catching one another hard. Whenever Alina hears her brother's thoughts she runs. Now, surviving amongst mankind is not a problem. Her Ridgerunner exists at the edge of reality; so stealing money from ATMs or banks, for that matter, is simply an easy task. The fun starts when the man that she had chosen to live with gets blamed for the theft and named The Magician, because the money just seems to disappear. The book follows a riot of science fiction tongue in cheek play and four times the same two traverse back through the same section of time trying to "get things right." Insanity is sure to follow on the poor earthlings caught up in the chase that these two aliens have.
