It has been very difficult keeping this news a secret. Thankfully, it has now been reported in Publisher's Marketplace, so here is the announcement:

Brown Gets Close to “Earth” at Custom House

For HarperCollins’s Custom House imprint, Geoff Shandler preempted world rights to David W. Brown’s One Inch from Earth. Brown is a contributor to the Atlantic and the book, which Dunow, Carlson & Lerner’s Stacia Decker represented, is about NASA’s Europa mission (established to launch a spacecraft into the orbit of Jupiter). Custom House said the book features “persevering scientists as its heroes, the planet Mars as the villain, and an unlikely savior in the form of a Tea Party congressman on a mission to find a second Garden of Eden on Jupiter’s moon.”

A lot of hard work went into this. The proposal took a full year to write—longer, in fact, than my last book—and involved more research, interviews, travel, and luck than I ever could have imagined. (There are no shortcuts when doing good work.) Of course, the hard part is yet to come.

My agent, Stacia Decker of Dunow, Carlson & Lerner Literary Agency, is one of the most competent, sharp, and fabulous human beings I've ever had the good fortune of knowing, and she parlayed the proposal into an tremendous book deal with the most exciting imprint in publishing today. (At lot of adjectives in that previous sentence, and every one is accurate.) I am over the moon at the idea of working with Geoff Shandler, who previously edited some of my favorite books ever, including Into the Beautiful North, a masterpiece by Luis Urrea.

Finally, I am honored to write this book and to tell the story of men and women whose work will transform science, philosophy, religion—you name it. One day we will all know their names, and it's a privilege to do my part in making that happen.

(I know this reads like an Oscars speech, but it's a pretty big moment for me, and I intend to live up to expectations.)
