I would have never picked up this book based on the cover, it looks ridiculous, but after only a few pages I was sold. Although the book does swap between the vibes of 90s S Club 7 baggy jeans and the good parts of 1920s domestic America, it sticks to them and the cutesy graphics coupled with concepts repeated with different wordings make topics memorable and the book interesting. I whizzed through this book partly because it was just fun. Great intro to Kotlin.
