I found this book a little challenging personally because there are so many new words in it. Luckily there is some consistent repetition with a lot of words, so the book gets generally easier as you progress. All of that said, as an adult, i found this story rather bland. Its clearly written for younger kids. Unfortunately im still hungry for a good language learning book that is more of a sci-fi/fantasy vibe
Very Boring, bad writing
I found these books incredibly dull to read. Unfortunately the author also does not really repeat new works, or make sure to introduce new words with enough context where you can surmise their meaning. So overall, i did not find this series very helpful.
