This was my first book on the subject of time travel, and I have been fascinated by it ever since. When compared to todays stories of such science-fiction, it is simplistic and almost childish, but I loved it, and have read it many times over the years. I enjoyed it more than any of Heinlein's other books.

I think that this was one of Heinleins better books. It kept my attention through the whole thing, and I really enjoyed it.

Still a personal favorite. Refreshingly chauvinistic and written before writers began mixing their pronouns. Pure fantasy (a guy and a cat? come on!) but still a good read for those of us still able to suspend our disbelief.

Great time travel novel.

I liked most of Heinlein's older stuff. Once he wrote "The Number of the Beast" he started writing too weird for me. This was one of his better ones. It is the first that I recall with a cat in it (he seems to have a reverence for cats) & an inventor who is a pretty smart guy but can still get himself into a world of trouble - and then back out again. Fun, quick read.

Robert Heinlein¿s output of novels and stories was so prodigious that it means most of us casual sci-fi fans can always find something he wrote that¿s new to us. So it was for me with The Door into Summer, a charming tale that combines cryogenics and time travel. Heinlein¿s touch here is light; this is a very narrow story focused on a brilliant engineer who finds himself mixed up in a business deal gone wrong, and who then combines resilience, genius, hard work and a bit of luck to see if he can straighten things out.

I had forgotten just how good Heinlein really was. While there's no Lazarus Long here, it's still something of a "time travel" yarn and almost believable. A really good read!

This was such a good book! Some of the technical stuff about how Dan planned and built his robots was over my head, as well as the last couple of pages that went way too deep into time travel after the story was basically already over. Other than this, I loved this book. It was interesting that the "future" that Dan traveled into was the years 2000-2001, since this book was written in the 1950's. A few of his guesses about what the future would be like weren't too far off from the truth, though some of it is still a bit far-fetched.

Entertaining and fast moving book. A fun look to what year 2000 seemed when looked from 1950s, some hits, mane mishits. Good prediction that there would be new concepts in language, and some things might might be hard to understand for someone who is transported 30 years to future. Irrittating subplot which might be considered as a bit pedophilic - hard to believe would be proper in a book written present time.

One of my favorite Heinlein novels for fifty years now, though the book's "future" has long ago receded into the past. It's 1970, and electronic wizard Dan Davis has developed (in a West Coast garage!) a functional household robot. But his nasty partner and his even nastier girl friend steal the invention and put Dan away in a "cold sleep" facility, where he sleeps away the next 30 years. When he awakes in 2000, he finds that descendants of his invention are everywhere. He assumes he'll never learn why, and never be able to tie up some very important loose ends from his old like, but then -- shazam! -- he finds a way back to the past. I suppose the characters are pretty two dimensional, but I loved them as a child and I still do. The plot is still a winner, and some of the "future history" looks surprisingly prescient.

What a fun book! Very nice, and ultimately, a very sweet book. Not hard core sci-fi by any means, but a pleasure to read.In 1970, Daniel Boone Davis is a very successful engineer, designing things like an automatic cleaning lady called The Hired Girl. He is prosperous and has a business partner and a secretary who together make up his company. He also has a cat, Pete (whose real name is Petronius Arbiter. As the story opens, DB Davis has just invented another household or otherwise automaton named Flexible Frank. He is living in LA at the time. Life is good. But it turns out that Miles (the business brains partner) and the secretary (Belle) force him out of the company and steal his stock, his patents and ruin his life as he knows it. Miles decides to take what is called "the long sleep," which is something akin to our notion of cryogenically freezing someone. But a last-minute stop at the home of Miles and Belle, who have secretly married, lands him in big trouble...Belle & Miles drug him & not only do they scare off Pete but screw Miles over even in terms of the safeguarding of his money during the long sleep. Dan wakes up and it's 2000. Everything, including vocabulary has changed over the last 30 years, and Dan finds out that the money he supposedly safeguarded was not good any more. In short, he's broke and must find a job. So he goes back to doing what he does best -- engineering -- and in the process makes some amazing discoveries while trying to find out about the people of his past. I won't go into it here, but suffice it to say, his discoveries have a tremendous effect on his life.I really enjoyed The Door Into Summer and can find nothing negative to say about it. Parts were laughable and it is a very quick read. I very much recommend it.

This was a very good book that I encourage others to read and it has a very interesting viewpoint on the study of time travel.

This was my first experience reading Heinlein, and I was pleased by the result. It's a pretty simple tale of betrayal and revenge, with more maturity than such tales tend to have. I'm pretty likely to try some more of his works later on.

An engineer is swindled out of his business by his partner and his fiancee and decides to put himself into cryogenic sleep for thirty years. He thinks better of it, but is then forced into doing so anyway.The cover copy overplays the revenge aspect of the story. When the protagonist awakes in the year 2000, he spends very little time contemplating revenge. It would be more accurate to say that in trying to make a new place for himself in the world, he discovers a secret which allows him to arrange a second choice at happiness. It is an adventure, pure and simple. I like Heinlein even when he's preachy (sometimes especially when he's preachy), but this is not one of those books, except possibly for a page or two at the end when he is trying to justify time travel. One has a hard time telling if he seriously expects this explanation to be believed or if he is jokingly asking the reader to suspend disbelief for the purposes of the story.The "Door into Summer" of the title refers to a description of how the hero's cat forces him to open every door in the house before he goes out in the winter, sure that one of them must lead to better weather. What I remember Heinlein for is usually his ideas, not his imagry, but in this he managed to find one that sticks.

Features the best feline sidekick (Pete) and the most believable time travel device in scifi.

Another great ride by Heinlein. It captured my attention from the outset and never let go. I am fascinated by an author like Heinlein's ability to predict what his future, our present will look like. Sure, he was wrong in many respects (household robots and cryogenics are lagging behind), but what he got right (e.g. AutoCAD) is amazing.
