As part of Amazon’s monthly deal of 100 Kindle ebooks for $3.99 or less, sci-fi master Robert A. Heinlein‘s The Door Into Summer is on sale for only $2.99.

Originally serialized in The Magazine of Fantasy and Science Fiction and published in hardcover in 1957, The Door Into Summer follows Daniel Boone Davis, a businessman in 1970 who gets screwed over six ways to Sunday by his partner and his girl and decides to take a 30-year cold nap in suspended animation. His plan to exact his revenge later on doesn’t quite work out so well, but that’s okay because there’s time travel. Time travel, people!! Gotta love Heinlein’s brilliance. I wonder if he imagined bad 70’s hair, too.
