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.

An amusing, lighthearted time travel romp, with a particular appeal for cat lovers. I don't know there was much here of real interest, apart from some of Heinlein's musings in the last few pages on the nature of free will, determinism and the existence, or not, of multiple universes. Also intriguing was his notion that the laws of the universe are capable of enforcing themselves, without any help needed from us humans, giving us a kind of free pass from worrying about paradoxes and the like resulting from time travel.

Liked this book way more than his more famous The Puppet Masters and Starship Troopers. It was light-hearted and whimsical, though quite a bit outdated.

Всі три зірочки Піту, котику, який п'є імбирний ель. Для винахідливого гг, який придумав спосіб як одружитися з дитиною, зірок немає

Для свого часу Гайнлайн добре писав, і це цікаво читати навіть зараз. Ну не дарма ж його дотепер вважають найкращим у цій ніші!

Рекомендую

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 story at all. It was fun, and it was refreshing to read such innocent prose.

Although some people might be offended, there was some narrative that would be considered non-PC these days, but was just part of life in the 'fifties. I actually found that quite refreshing too. I get so irritated by the over-sensitivity to political correctness these days. You can't even tell a good Irish joke, or drop your pants in a US bar to proudly show off your British tattoo, these days, without drawing comments from the puritans.

The story was great right up until the final chapter. This was a bit of a damp squib, Heinlein felt that his hero had to justify and explain his actions and how several instances of himself could coexist. I would have been far more satisfied with the explosive ending which could so easily have been there.

Having said that, I would strongly recommend this book to all lovers of time travel and sci-fi books.

4.5⭐

Непогана і дуже проста наукова фантастика, цікаві повороти сюжета, які тримають в інтризі, але деякі моменти я все ж таки передбачила

Дуже підійде тим, хто тільки хоче увійти в жанр наукової фантастики – бо дуже легкий вхід і доволі простий сюжет

Robert A Heinlein is one of the influential SF authors, whose masterpieces influence later SF generation. The Door into Summer is not as prominent as Stranger in a Strange Land, but still it is a profoundly marvelous Sci-fiction that I've read so far. I wouldn't explicitly spoil what is the story about. This book is a very classic revenge story with some Sci-Fi settings in a speculatively high-developed future. The Sci-Fi setting explain why our protagonist was swindled by his former partners. Heinlein also has used Time travel in The Door into Summer like many Sci-Fi authors would choose to. The explanation of Time Travel would be adequate to deliberately elaborate the whole story.

I think the concepts are quite interesting in this book such as ' Cold Sleep' and automotants; although about AI isn't fully explained in details for me, more like a appendage in The Door into Summer. If you like cats, you may like this book more.

Me gustan las primeras historias de Robert Heinlein con su estilo narrativo de monólogo continuo que solo él podía lograr bien. "Puerta al verano" es un libro de este tipo, publicado originalmente alrededor de 1957, ofrece una visión interesante del "futuro" de 1970 y del "futuro" aún más lejano del 2000. En una entrevista sobre el libro, dijo que después de tener la idea, solo le llevó 13 días escribir Puerta al verano. Imaginate lo que es escribir un "clásico" en solo 13 días.

La novela se publicó en 1957, pero Heinlein imagina una América en 1970 y nuevamente en el año 2000. Nuestro héroe, Daniel Boone Davis, es ingeniero e inventor, y un personaje típico de gran parte de la ciencia ficción de la década de 1950. Tiene un gran sentido de la libertad personal y autosuficiencia; un individuo que hace las cosas a su manera, que no tiene miedo de dar patadas contra la autoridad corporativa y que no tiene miedo de correr riesgos. Inventa una serie de ayudas para el hogar que tienen éxito. Su secretaria y su gerente comercial lo engañan con las ganancias de su empresa y lo engañan para que tome el sueño FRIO (animación suspendida) durante un período de treinta años. Se despierta en el año 2000 todavía con la necesidad de usar sus habilidades de ingeniería, pero el mundo ha seguido adelante. Consigue un trabajo en una rama de la empresa que fundó y le intriga que las patentes originales de sus máquinas más vendidas aún lleven su nombre. Descubre que el viaje en el tiempo se ha intentado con éxito y se abre camino para volver a 1970 para descubrir qué sucedió y recoger a Pete, su gato (todo un caracter)

Ahora bien, ¿es este un “clásico” de la ciencia ficción? Este libro aparece en algunas listas de los mejores. Me cuesta decidirme. Es muy entrtenido y es difícil para mí señalar algo que no me gustó. Sin embargo, cuando lo comparo incluso con otros libros de Heinlein, parece quedarse corto. La Luna es una cruel amante sigue siendo uno de mis libros de ciencia ficción favoritos de todos los tiempos. Incluso Forastero en tierra extraña de Heinlein me parece más un "clásico". Estos "clásicos" tienen un mayor alcance, y tal vez ese sea el encanto de Puerta al verano: es sencillo pero impecable.

Una cosa más para discutir: ¿El libro esta desfasado? Estamos tratando con un libro de más de 60 años, por lo que hay referencias fuera de fecha. El futuro imaginado de Heinlein está vacío de ordenadores e Internet pero soy un gran defensor de la lectura de libros antiguos. No podemos esperar que los libros antiguos coincidan con nuestra visión del mundo, sino que debemos dejar que amplíen la nuestra.

I think I've read too much Heinlein as this seemed pretty formulaic for him. Libertarian everyman outsmarts the capitalist bureaucrats. Yawn.

Well, that was lame...and weird. I would have given this a 3, but that ending was hella strange.

Honestly, I couldn’t get into this book and was mostly bored the whole time.

Davis takes the “long sleep” in 1970, wakes up 30 years later, and nothing exciting comes of it other than needing to get a job and figure out what happened to his inventions and stocks. There is barely any discussion of the changes that occurred over the 30 year period. There is mention of a large amount of new jargon, but we get one new term: “movies” are now “grabbies.” ?? And there are some robots.

The plot is straight up silly. Davis sleeps 30 years, gets his inventions ripped off by his crazy con ex, realizes that he himself was the inventor and wasn’t actually ripped off, travels back in time to invent the things, then goes back to sleep for another 30 years to marry a little girl.

Now let’s discuss the little girl. Ricky. Wtf was that? Davis knows Ricky as a child, he never meets her as an adult until she wakes from the long sleep, which he led her to do. Before he ever meets her as an adult, he wants to marry her. When she is 11 and finds out he will be asleep the next 30 years, she gets sad, decides/is persuaded to take the long sleep also, and asks him to marry her when she wakes up. He agrees and tells her that that’s the exact reason he is doing everything that he has done. ??? And he talks about how her breasts have not filled out yet and how she’s adorable. I tried to be objective about the situation but that was so weird to me. He only knows her as a child. I’m not offended by taboo topics, but wtf kind of goal is that for a main character? His literal goal is to marry her and that is the end of the book.

This is a weird ass book that was too all over the place for me. I don’t know what to think about Heinlein. And this has an average score of 4 stars on Goodreads...why??
