Det är en lång sträcka, men det är möjligt att du tänker på Gordon R. Dicksons Time Storm
från en av recensionerna på Amazon-länken ovan:
Gordon Dickson's "Time Storm", first published in 1977, is an excellent post-apocalyptic novel concerning the catastrophic after effects caused by on-going time storms (or time lines that appear as, and are called in the book, 'mistwalls') that continually sweep across sections of the Earth, as well as throughout the universe. As a time storm passes, a large swath of land becomes forever changed in time. A side effect is that for most of the population these time sweeps are deadly.
Luckily (or you would have no story), a small percentage of the population (including a few animals) seem immune to the deadly effects of the time storms. The three main characters; the protagonist (Marc Despard), an autistic teenage girl (known as 'Girl'), and a leopard (called Sunday), are all richly defined.
This story begins with the three unlikely partners traveling across country where they cross area after area that has been changed in time. The people (and/or creatures) that have been 'deposited' into the effected areas (if there are anyone at all), are either from some point in the future or from the past, but like any post-apocalyptic story, few are friendly. Even the survivors of his own time can be, and usually are, extremely dangerous.
Här är korsningen mellan två mistväggar (eventuellt dina "dimma eller dimma"):
Kapitel 9:
It did not take long to reach the end of it. I kept on a little further, however, not wanting to turn the corner until I could see behind it. But though we kept going further and further, we still did not seem to quite clear the end. Finally, I saw why. We were not going to be able to see behind that mistwall after all. Here at what I had thought was its point of termination, it had either bent to the right and continued, or run into another mistwall going off at an angle in that direction.
At first, all I felt was disappointment that I was not going to get a look behind it. Then it occurred to me that perhaps the reason neither mistwall nor mistwall section had been moving had been because each had butted up against the other; and the two time change lines coming together had somehow created an unusual state or condition that had halted them both. The moment that I thought it, I was hungry to see what was behind the intersection of those two mistwalls.
Det finns faktiskt ett hus bak murskärningen, bebodd av en ensam kvinna och hennes förpackade utbildade hundar. Mannen, flickan och leoparden var till fots (på cyklar, faktiskt, en av de få post-apokalypshistorierna där cyklar används) vid denna tidpunkt i historien men i början körde de en panelbil.
