DD-13 is a universe where every mystery is connected, every detail has a purpose, and every move is part of a plan years in the making. Across thirteen interconnected books, you will witness events beyond imagination, where nothing is accidental and every truth has been meticulously engineered. For the first time, the number of physical books published will not be determined by the publisher or the author, but by the readers themselves. Through interactive challenges you become more than a reader—you become part of the plan.
