 As was the case with many of Heinlein's books, "Starship Troopers" was completed in a few weeks.It was originally written as a juvenile novel for New York publishing house Scribner; Heinlein had previously had success with this format, having written several such novels published by Scribner.The manuscript was rejected, prompting Heinlein to end his association with the publisher completely, and resume writing books with adult themes.
