The door to the summer. Heinline R. E.

Each living creature on Earth seeks to find a door to the summer. Where it is warm, there is no cold, there is no war, hatred, resentment. Where a friend will not betray you, the bride will not deceive. In the famous Robert Heinlin novel, Daniel Bun Davis and his cat Petronius Arbiter are looking for such a door in the summer, a completely polite animal - when he is not stroked against the wool and does not clap on the back. To find the door to the summer of the cat and his owner has to overcome time, and the time is severe - not with everyone it is ready to enter the game, preferring those whose heart is open to the world.
