A previously unpublished novella by Kurt Vonnegut will be released on Friday by RosettaBooks, close to 60 years after it was written, the publisher said on Thursday. The 22,000-word novella, “Basic Training,” was rejected by the Saturday Evening Post in the late 1940’s, long before Mr. Vonnegut had become famous through works such as “Slaughterhouse-Five” and “Cat’s Cradle.” After Mr. Vonnegut died in 2007, a trove of his unpublished work remained in Indiana, where he was born. RosettaBooks chose the novella from hundreds of other works that Mr. Vonnegut’s literary executor had made available.

A statement by RosettaBooks described the novella as a book that demonstrates Mr. Vonnegut’s “trademark grand themes: the lunacy of kings, the improbability of existence, the yearling hero’s struggle with duty and love and the meaning of heroism.”

It will be released exclusively through Amazon as a Kindle Single at a cost of $1.99.
