Easy Reader, Level 4. Only available as an app on phones. This is about 4 young people on a holiday in the Greek area Máni, who discover a mysterious cave.
Exciting story with some history. This takes place mostly 20+ years ago, when the (real) area was pretty deserted. I found it on Google maps, and its full of vacarion homes now, as the storyteller discovers in the end. But that must help Greece's ailing economy. Again, just the right level for me. I'm getting better at guessing means from parts and context (so i read the last 2 chapters quickly, but will go back to reread them and do the exercises. I don't like the writing exercises, though, that seem to expect you to reproduce the text. But fill in the blanks and arrange sentences in correct order are good comprehension exercises.
