This book documents the journey of these two authors\ scientists from their realization that Pluto was scientifically interesting but still unexplored in the 80s to the actual flyby in 2015. It starts with a loving tribute to discoverer of Pluto Clyde Tombaugh, whose ashes are on the probe itself, then it proceeds to tell an exciting tale of actually getting it there.

Contrary to popular belief the journey of New Horizons didn't start in 2006. It's start was painfully in 1989. Yes, that is how long it apparently takes. From the acceptance that someone should send a probe to Pluto, through a large number of mission revisions (you have to keep up with the trends), one cancellation, than building it and launching it, and finally making sure it does its job when it gets there, who would have guessed that the rocket science and design were the easy part.

Unfortunately this book was written too early to tell us the tale of the Ultima Thule flyby and all of the science that was obtained, but still a great read.
