Chekhov For Emergencies.
I couldn't find 'kindle' but I did find something similar called 'stanza' which I could download in seconds for nothing. I then went on to Gutenburg and found several publications under Chekhov including something I've had my eye on for some time - one of his short novels called the Duel. So, in a few minutes I had my emergency Chekhov book. In fact I could have virtually any book that I liked (if I could find kindle and hence amazon) all on a tiny screen 8cm by 5cm.
I can slip it into my handbag since it weighs very little, and yet, surprisingly, it is quite easy to read, and the page turning is fast. I can brighten or darken a page by stroking the screen up and down, go forward or backwards with a tap in the corners, and when I put it down my place will be saved. Now all I have to do is to remember to keep it fully charged (my big failing, I'm afraid).
