Amazon.com Book Description (ISBN 0670061344, Hardcover)

It is 1943, and 11-year-old Dewey Kerrigan is traveling west on a train to live with her scientist father—but no one, not her father nor the military guardians who accompany her, will tell her exactly where he is. When she reaches Los Alamos, New Mexico, she learns why: he’s working on a top secret government program. Over the next few years, Dewey gets to know eminent scientists, starts tinkering with her own mechanical projects, becomes friends with a budding artist who is as much of a misfit as she is—and, all the while, has no idea how the Manhattan Project is about to change the world. This book’s fresh prose and fascinating subject are like nothing you’ve read before.

Ellen Klages’s award-winning debut novel is now in paperback!

It is 1943, and eleven-year-old Dewey Kerrigan is en route to New Mexico, to live with her mathematician father. Soon she arrives at a town that, officially, doesn’t exist. It is called Los Alamos, and it is abuzz with activity, as scientists and mathematicians from all over America and Europe work on the biggest secret of all—“the gadget.” None of them—not J. Robert Oppenheimer, the director of the Manhattan Project; not the mathematicians and scientists; and least of all, Dewey—know how much “the gadget” is about to change their lives.
