Product Description

"Not only America's premier writer of speculative fiction, but the greatest writer of such fiction in the world. He remains today as a sort of trademark for all that is finest in American imaginative fiction."
--Stephen King

Electronics engineer Dan Davis has finally made the invention of a lifetime: a household robot with extraordinary abilities, destined to dramatically change the landscape of everyday routine. Then, with wild success just within reach, Dan's greedy partner and greedier fiancée trick him into taking the long sleep--suspended animation for thirty years. They never imagine that the future time in which Dan will awaken has mastered time travel, giving him a way to get back to them--and at them . . .

Once again, the author of Stranger in a Strange Land and Starship Troopers displays his genius. The Door in to Summer proves why Robert Heinlein's books have sold more than 50 million copies, winning countless awards, and earning him the title of Grand Master of Science Fiction.

"Heinlein . . . has the ability to see technologies just around the bend. That, combined with his outstanding skill as a writer and engineer-inventor, produces books that are often years ahead of their time."
--Philadelphia Inquirer

"One of the grandmasters of science fiction."
--The Wall Street Journal

From the Publisher

After Heinlein passed away, Del Rey published a book called Grumbles from the Grave, and I had the great pleasure of working with Virginia Heinlein on gathering photos and other material to accompany the letters and text that made up the book. While at her house, I was introduced to a cat named Pixel.

It must not have been this particular feline that inspired the cat in A Door into Summer, but it certainly could have been, and I re-read the book as soon as I could.

If you haven't read Henlein, you haven't read science fiction, and if you haven't read this, you haven't read Heinlein. It's the quintessential time travel-paradox story. It's exciting, it's fun, and of course, there's the cat.

5.0 out of 5 stars The best time travel novel ever written, November 17, 2002

By	Daniel Jolley "darkgenius" (Shelby, North Carolina USA) - See all my reviews (TOP 50 REVIEWER)    (REAL NAME)

This review is from: The Door into Summer (Mass Market Paperback)

There have been many science fiction novels written about time travel, but The Door Into Summer is my pick for the greatest among them. It comes remarkably close to conveying the very theory of the subject in layman's terms. I'm not saying Heinlein's arguments are correct, but they darn near make sense. The experiment with the two coins and with the two guinea pigs (just one, actually) is fascinating, and Heinlein's introduction of several paradoxes in the protagonist's actual temporal dislocation lends his science even more believability. Time travel doesn't even enter into the pages of the first half of the novel (not directly, at least), but the whole story is totally engrossing from the very start. Dan is an engineer and a darn good one. His inventions have been designed with the view of easing the housework of women everywhere: Hired Girl cleans floor; Window Willie washes windows, and Flexible Frank, his newest creation, will be able to do just about anything around the house, from changing a diaper to washing dishes. Life seemed to be treating Dan pretty well. Then his fiance and business partner swindle him out of their business, and he decides to take the Long Sleep (cryogenic suspended animation) for thirty years so that he can come back to chastise an ex-fiance who will be thirty years older than he will be. Of course, he won't do it without his best friend Pete, his feisty, ginger ale-loving tomcat and true friend. He sends his remaining shares in the company he created to his partner's young daughter Ricky, his only other friend in the world, trying to make sure that those don't fall into the wrong hands as well. His only mistake is in confronting his traitorous friends one last time. He gets the Long Sleep all right, but he wakes up in 2000 without any money and without Pete. He starts trying to find Ricky and start a new life, but he eventually, prompted by subtle clues to things that will have taken place, works up a plan to journey back in time and change things-of course, he won't really be changing things because they have actually already happened. It's so much easier to time travel when you know everything you will have done before doing it.

I love this novel. It's brilliant the way he works in clues to Dan's future past, and Heinlein's discussion of time travel is enough to make anyone a fanatic about the subject. When I think about time travel, I continue to think of this novel and its simple experimental analogies of coins and guinea pigs. It's mind-boggling yet completely comprehensible. I also love animals, and good old Pete is one of the most memorable feline characters in the universe of fiction. Finally, the concept of the title is well-nigh epiphanous (if I may coin a word). Dan explains how Pete would make him open every door in his house whenever it snowed, convinced that behind one of those doors it will be summer time. Dan describes all of his adventures as his own search for the Door Into Summer. The only possible explanation I can formulate as to why this novel did not win the Hugo for best science fiction novel of 1957 is the fact that Heinlein won the award the previous year for Double Star and could not comfortably be given the award two years in a row. The Door Into Summer is much better than Double Star; in fact, it is much better than all but a handful of science fiction novels ever published.

5.0 out of 5 stars Time Travel at Its Best, September 22, 2003

By	A. Wolverton (Crofton, MD United States) - See all my reviews (TOP 1000 REVIEWER)    (REAL NAME)

This review is from: The Door into Summer (Mass Market Paperback)

At the time he was writing, Heinlein's books were so much better than all the others because he was so much smarter than most other writers. He thought things through first (which many others did too), but then he added an element that many other sf writers didn't (and some STILL don't): humanity.

Dan Davis, an inventor, narrates the story. He's a brilliant inventor and has come up with some pretty amazing gadgets, including Hired Girl, a robot who cleans, sweeps, vacuums, mops, and generally works all day long without supervision. Dan's problems begin mounting when he learns he's been betrayed by his partner. And to add insult to injury, Dan's fiancée is in on the betrayal as well. As if betrayal alone isn't enough, the two conspirators have Dan placed into a 30-year suspended animation. Dan wakes up 30 years later and is focused on one thing: revenge.

Now lots of authors could have taken the above premise and come up with an entertaining story. Heinlein did this and much more. He shows us that change (for individuals and for all humanity) is difficult, but not impossible. The future is full of challenges, but no matter how much technology changes, no matter how much language, currency, and trends change, man's basic instincts and attitudes remain constant.

Heinlein also tackles the implications of time travel better than anyone else from this period. (The book first appeared in 1957.) The problem of time travel is well thought out and logical. (Wish you could say that about every time travel story.) If you haven't read Heinlein, or if all you've read is `Stranger in a Strange Land,' `Starship Troopers,' or `The Moon is a Harsh Mistress' (all great books), treat yourself to a fun, intelligent read from one of the true masters.

5.0 out of 5 stars A wonderful, charming SF tale, September 8, 2003

By	John S. Ryan "Scott Ryan" (Silver Lake, OH) - See all my reviews (TOP 500 REVIEWER)    (REAL NAME)

This review is from: The Door into Summer (Mass Market Paperback)

I rank this among Heinlein's three absolutely magisterial novels (the other two being _Double Star_ and _The Moon is a Harsh Mistress_). Such judgments are notoriously subjective and controversial. But I feel safe in saying that any SF reader will find something to enjoy in this marvelous story.

It's part SF, part fairy tale, and part just plain good storytelling. Engineer/inventor Daniel Boone Davis and his feline companion Petronius the Arbiter are two of Heinlein's best-realized characters; the plot here is well-conceived and evenly, swiftly paced.

In case you haven't read it, I won't spoil it for you. The setup is that Davis has just been rooked by his best friend and his fiancee, and he's out to do something about it. What happens then is the story itself, so I won't tell you; I'll just say that the time-travel aspect is worked out every bit as neatly as in "By His Bootstraps", and the tale is one of Heinlein's most humane ever. I've read it more times than I can count, and there's a bit near the end that _always_ gets me. (You'll know what I mean when you get there.)

Heinlein wrote this at the peak of his talent. If you haven't read it yet, don't miss it.
