I love this book, but it is a little pricy. Overall, I think it is worth the cost and is a unique book. The QR codes linked to the Youtube playlist are useful. Being able to watch a video about the plant made it easier to identify. It appears the author updates the playlists over time. I noticed that videos were being added to playlists I had already watched. The addition of the QR codes is a cool concept, I am really happy with my purchase.
