There is a tower that calls chosen individuals known as "Regulars" with the promise of fulfilling their greatest dreams. Wealth, fame, authority, or something greater than all of these await those who reach the pinnacle. Bam is a twenty-fifth-year-old boy who has spent his entire existence in a dark cave, a filthy fabric, and an unattainable light. So when a girl called Rachel appeared in the light, his entire world altered. He learnt a lot about the outside world via Rachel, whom he became good friends with. But when Rachel tells him she has to leave him to climb the Tower, his entire world crumbles around him. He sets his sights on the tower, vowing to pursue her no matter what it takes.
