New York: Doubleday, 1957. First Edition. Octavo. Item #028382
188 pages. One of the masters of time travel writing, here Heinlein also explores a situation with his adopted daughters which many think was influenced by Nabokov's Lolita (an idea hinted at in Back to the Future) and perhaps practiced by a writer-filmmaker. One the most important and originally neglected of Heinlein's earlier works. Bound in red cloth, spine lettering yellow, a near fine copy in in unclipped pictorial dust jacket with edge wear, chipping to spine ends, spine faded, and a few short tears.
