It is wild to think that Dan Brown, author of such thrillers as [b:The Da Vinci Code|968|The Da Vinci Code (Robert Langdon, #2)|Dan Brown|https://i.gr-assets.com/images/S/compressed.photo.goodreads.com/books/1579621267l/968._SY75_.jpg|2982101] wrote not only a wholesome children's book but a collection of poetry, and also HE COMPOSED A SYMPHONY. Ok, calming down, this is a good book and symphony, and my kids love the music and now are interested in hearing other symphonies, and the app is rather magical. Lovely addition to our bedtimes. From a public librarian perspective, I would appreciate an adition of this book that did not require a smart phone. An in-book player would be good.
