Now available as a hardback, paperback, and ebook!

In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space is available everywhere at Amazon, Barnes & Noble, and all book vendors. All editions can also be purchased directly from the ebook publisher ebookit, thus giving the author a bigger percentage much sooner.

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.”
— Robert Zubrin, founder of the Mars Society

From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back. Unfortunately, that is exactly where that journey takes him.

A riveting new science fiction book by Robert Zimmerman that captures the heart of the human spirit, willing to push forward no matter the odds, no matter the cost.

Available everywhere for $3.99 before discount at Amazon, Barnes & Noble, all ebook vendors, or direct from my ebook publisher, ebookit.

So now I stand on earthside shore,
And wonder what I am.
I must go out and find my home.
The journey’s what I am.

Chorus:
O Pioneer! O Pioneer!
Where do you go from here?
O Pioneer! O Pioneer!
The stars are far too near.

The new edition of Genesis: the Story of Apollo 8 includes a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon, from any other bookseller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for details. The ebook is available everywhere for $5.99 before discount at Amazon, or direct from the publisher, ebookit. If you buy from ebookit the author gets a bigger cut much sooner.

The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

“Not simply about one mission, [Genesis] is also the history of America’s quest for the moon… Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America’s greatest human triumphs.”
— San Antonio Express-News

Leaving Earth is available as an inexpensive ebook!

Leaving Earth: Space Stations, Rival Superpowers, and the Quest for Interplanetary Travel can be purchased as an ebook everywhere for only $3.99 before discount at Amazon, Barnes & Noble, all ebook vendors, or direct from ebookit. If you buy it from ebookit, the author gets a bigger cut much sooner.

“Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened.”
— Arthur C. Clarke
