Like the first book, both the front and back cover are (apart from the copper leaf) completely colorable! This feature was one of the main things I liked about the first book, so I'm glad to see it make a return. Also, like the first book, this book has an actual story with words. I liked the story, but I didn't find it necessary to my enjoyment of coloring in the book at all. Finally, this book also includes a Visual Index in the back! This was honestly my favorite feature from the first book and I am beyond happy to see that they included it in The Time Garden as well!
Overall, The Time Garden was an excellent addition to this series of adult coloring books. The pictures are gorgeous and it has a lot of handy/fun additions. I gave The Time Garden 5 out of 5 stars; I can't wait to see what Daria Song publishes next!
