No problem, glad you liked it!

Great, thank you for sharing! I didn’t know you could download the audio without buying the book, but this seems to be fairly common among publishers. My guess is that most customers view the book as the main product and then audio is just a bonus, and so the publisher saves a lot of hassle by offering it as a free download. I was familiar with the book, although I haven’t read it, through Diane Neubauer’s review of lots low-level graded readers here.
