The series started in 2009 with Post-human, followed by it's sequel, 2011's Trans-Human, and then leading to the prequel, published in the summer of 2012, Sub-Human. The trilogy can be read in the order of publication or in the chronological order of the entire epic story. The ebook is ordered according to the narrative, but reading it in the order of publication is its own, rewarding experience. It's all up to your preference.
Readers have taken to calling this the "Human Series," and why not? It's the story of humanity's future, both the possible bliss, the possible torment, and all of the in between. It might expand your view of what "human" really means, it might make you consider the pleasures and pains of immortality, and reflect on the extraordinary benefits and profound danger of strong A.I. All of this delivered in an epic series, paced faster than most novels, with twists and turns around almost every page, and a set of characters with whom you'll fall in love.
