post-human series

I collected the Post-Human Series into this volume so that I could give readers a little more bang for their buck. Reading the books in this volume is the cheapest way for new readers to access the series.


Post-Human was published in 2009, followed by Trans-Human in 2011. It caught fire in February of 2012 when the ebook revolution was at its height. The enthusiasm of readers catapulted me from being a part-time "weekend" writer to becoming a full-time author. It changed my life and I owe it all to reader support. I added two more books, Sub-Human in 2012 and Human Plus in 2013. These two volumes contain the four books in their entirety.


The Post-Human Series has been referred to as the "Human Series" by some reviewers and I can certainly understand why. At its heart, it is about the human condition in a future that will come. While no one can say exactly what form it will take, strong artificial intelligence, major breakthroughs in genetics, the emergence of nanotechnology, and our ability to eventually make ourselves immortal are all eventualities that, barring an extinction event, are on the horizon for this century. Post-Human takes us on a tour of the pleasures and pains of what will be the most turbulent time in the history of our species. It will at once entertain you and make you think. What is to come indeed? Welcome to the Post-Human era.
