Tower of God

The Tower at the centre of the world chooses who climbs it. The chosen, called Regulars, work their way up floor by floor with the promise that whoever reaches the top gets anything they want — wealth, throne, love, escape. Twenty-Fifth Bam has spent his entire life in a cave with a girl named Rachel for company. The day Rachel leaves him to climb the Tower, Bam follows her without being chosen — and the Tower opens its gates anyway, marking him as an Irregular, a class of climber that has historically broken whatever floor it stood on.
