An enjoyable SF story from a Grandmaster.

The novel's protagonist, Daniel B. Davis, was a precursor to Hugh Farnham and even Lazarus Long somewhat, though Long was introduced earlier in 1941's Methusaleh's Children. Actually, Davis (and others) are thinly disguised Heinlein: fiercely individualist, libertarian, technically savvy, hard working yet innovative, resourceful, wise cracking, and with a horn dog libido that would make a porn star blush.

I wonder if Door Into Summer used some of the same

I'm a little surprised I don't seem to have posted a review of this one before. I read this book "way back when". I probably read it first when I was in high school or just after. That would probably be the 1960s. I went through a period when I discovered Heinlein and ran through everything I could get my hands on by him. Some I didn't care for, some I liked and some I loved.

Many people place this in his so called "teen reads" but there is some question about that due to some of the subject matt

I liked it, but it was suggested to me I shouldn't give four stars to every single book I enjoy, so here it goes for Heinlein. I really had no issues with "The Door Into Summer", and Heinlein is still one of my favorite SF masters after this.

I enjoy books that feature engineers as protagonists, and here we have one proto-geek singlehandedly inventing robotics in the 50's and failing rather spectacularly in the human relations department. Later on, there's some time travel thrown in and some cryo

I really enjoyed this book from beginning to [almost] end. The reason for the "almost" will become apparent.

The story of time travel by various means was excellent. When reading this story, you should remember that it was written in the 1950s. Some of Heinlein's predictions are amazing, and some are way off the mark. It's amazing to follow his line of thinking though.

You can see an outline of the plot in the description. It is fairly predictable, but that didn't detract from my enjoyment of the

Somewhat unusually for Heinlein, this is a cute, fun book which doesn't try to ladle a bunch of right-wing ideology down your throat, or O.D. you on dubious sex. There's some time travel, a sympathetic main character, a Bad Girl, and a cat who steals the show every time he appears on stage. He even gets the title: the reference is to his endearing habit, during winter months, of making the hero open each door in the house in turn, just in case one of them happens to lead into summer...

I didn't read this book with the intention of writing a review, so you'll excuse me if I don't go into great detail. Let me just summarize "the feel" of the book...

It is not very often that I read a book that makes me smile the entire time I'm reading it; this is one of them. From the hilarious anachronisms of the 1950's Futurist to the brilliant side-kick cat, Pete. (Cat lovers will appreciate this book on a completely different level than other readers).

Another old favorite picked up as a downloadable audio book from the library. It was quite enjoyable in this medium & the reader was very good. Originally published in 1957, it is set in 'the future' years 1970 & 2000. The idea of traveling into the future via 'cold sleep' was a pretty popular until sometime in the 70's, but cutting edge at this time, I think. Haven't heard about it in humans for years.

The hero, Dan, is an engineer & inventor. His genius isn't in break through techno

I liked it far less than my previous RAH reads of The Moon is a Harsh Mistress, Starship Troopers, or even Stranger in a Strange Land.

The story - silly technician looses his garage corporation predictably to greedy woman and former business partner - wasn't very good with all that implausible back and forth through time and hibernated sleep. RAH rode that SF trope but didn't motivate it well enough; a lot of less riskier and far easier solutions to the protagonist's problems lay on hands. Especi

Are you a cat person? If yes, you’re definitely in for a treat. Pete is an amazingly written cat character if there ever was one. Yes, cat lovers will surely appreciate this one. Cat owners will understand that cats like Pete are as rare as true love and only come once in a life time, if we’re lucky, hence they will understand what makes Pete so special to Dan, his owner. However, even if you happen to hate cats, I’m sure you’ll appreciate the ingenious way Pete is described. That’s just plain g ...more

I first read this many years ago—probably about the time in which it is set: it was published in 1957 (just before I was born) but most of the story is set in 1970 and the rest in 2000/2001. The only thing that really stayed in my memory was the reason for the title.

Dan Davis once lived in Connecticut in a house with twelve doors to the outside. In Winter, his cat Pete (Petronius the Arbiter) would make him open every door, looking for the one that led to Summer. Pete's not present for the

For today's standards it is a rather short novel with Heinlein still in his early stage, trying to develop the style that later led to his major works, and short is better in this case. It is told first person perspective and this makes things difficult for the narrative part but better for the introspective one.
There are no discussions of time travel issues or paradoxes to be solved, still the book is enjoyable, but if you want science fiction with any depth or emotional resonance, don't expect

A very fast paced story line with drama for days. 'The Door Into Summer' was written in 1957 with the plots story based between 1970 - 2001. Robert A. Heinlein had to do a lot of predicting to paint a believable world set in 2001 in which he succeeds creating a believable account of time travel which isn't over the top or far fetched as most time travel novels seem to be. The main character Dan Davis is extremely well written, charismatic, smart, wise and quick witted, making him very enjoyable ...more

The Door Into Summer (1957) is an immensely enjoyable time-travel story told effortlessly by Robert A. Heinlein long before he turned into a crotchety, soap-box ranting old crank who had a very unhealthy obsession with free love and characters going back in time to hook up with their mothers (gross!!).

So back to this book. It’s the story of Daniel Davis, a hard-working engineer in 1

Three and a half stars, so I guess my four stars will stand.

I read this as a teenager and have always remembered it as a love story. And I still think that. The difference is, this time I'm certain that the "love story" in this book is between narrator Dan and his cat, Pete, and definitely not between Dan and (view spoiler).

Cuando leo una novela de la edad de oro de la ciencia ficción, suelo verla de forma crítica, normalmente están muy bien escritas (con una prosa más elaborada que las actuales), pero casi siempre contienen elementos anacrónicos, cosas que a un escritor actual no se le ocurrirían porque simplemente el tiempo ha hecho que ciertas ideas resulten absurdas y sin sentido.

This is a very accessible and entertaining Heinlein read.

It is set in what was then a couple of decades into the future: 1970. The protagonist ends up travelling 30 years into his future by means of a cryogenic sleep to wake up in the year 2000. Reading this book in the year 2015 gives one quite a different perspective than one would have had reading it when it first came out. One can look back and judge how the authors vision of those years diverged from reality.

This is an optimistic book. Op

La historia del libro toca uno de los clichés típicos del género, los viajes temporales. Pese a no ser gran fan de este tipo de novelas lo cierto es que me ha parecido original. La única pega que le podría en

Prava knjiga za ulazak u Novu godinu.
Motiv "hladnog sna" i jednosmjerno - dvosmjernog putovanja kroz vrijeme zadržava pozornost čitatelja sve do kraja. Iako je neke stvari moguće pretpostaviti prije samog kraja, pripovjedački stil Heinleina nadoknađuje sve nedostatke i potvrđuje činjenicu da se radi o jednom od najboljih SF pisaca.
Sposobnost koncentriranja priče na "običnog malog" čovjeka stavljenog u neobičnu situaciju je ono što cjelinu čini kvalitetnom i svakako vrijednom čitanja.

Oh, 1950s science fiction - is there nothing you can't do?

One of the downsides to our modern information age is that we have so much information available to us. If I see a reference on a blog or in a book that I don't know, it's a quick hop over to Google or Wikipedia to find out what it is, and if it's really interesting I can find myself learning about something I never knew before. And so, if I want to know more about cold sleep, robotics or time travel, there's a whole host of ways that I c

Heinlein is a standard for old sci-fi. I think I may have read this before, but the reread was still enjoyable. Until the end. I always really get a kick out of vintage sci-fi where the author makes predictions for the future. It's especially fun when some of those predictions are almost correct. Heinlein foretells debit cards, for instance, even though he describes them in a cumbersome way.
