There is a type of music that’s made for the brain. Another type of music that’s made for the heart. And another type of music that’s made for the hips and feet. If a person wants to go dancing, they probably won’t go to a Chopin concert. There’s a reason lullabies don’t have a samba or salsa rhythm.
It’s the same for books. Which means almost any book is worthy to make because we don’t always know what people need and when they need it.
