On the plus side, it is a graded reader that starts relatively simply and then progresses as you work through the stories in the book. On the down side, they were the kind of stories that annoy me and until you get near the end of the book they are very short. The result was that it took me a long time to finish this book. However, that is just me. If you are a fan of Maupassant (not actually in the book), leprechaun trickery and other such stories, you may like this a lot more than I do. I will say in its favour though that the first story is a lot more interesting than the first stories of many other graded readers. It’s just that there was a sameness across the set of stories that made it tedious for me.
From a readability perspective I give it a 6.7 (based on the first ~100 words), which sits with various other graded readers including some A1 teen readers on the scale. So it is suitable reading for A1+ learners.
