The Door into Summer, by Robert Heinlein, is the author’s last adult novel written before his arguably three most famous works: Starship Troopers, Stranger in a Strange Land, and The Moon is a Harsh Mistress. The book benefits from the strong points that every Heinlein novel displays, but in other ways it almost feels like the author was holding back. Like Alfred Hitchcock, Heinlein had some great works mixed in with a lot of decent ones, and the present novel fits squarely into the latter category. In researching it, I came across a quote by John W. Campbell that sums up for me how I feel about certain Heinlein novels, The Door into Summer included: “Bob can write a better story, with one hand tied behind him, than most people in the field can do with both hands. But Jesus, I wish that son of a gun would take that other hand out of his pocket.”
The narrator, Dan Davis, is a gifted engineer who cannot see eye to eye with his business partner and best friend, Miles Gentry. Miles and Dan’s fiancée, Belle, conspire to steal Dan’s company from him and then send him into hibernation for thirty years. He wakes up in the year 2000, destitute, but begins working to build himself back up and maybe get some revenge. Along the way, as Dan investigates what has happened since he was put into the “Long Sleep,” strange clues begin turning up, indicating that there is more going on than he may realize.
